I just changed the engine in my 96 Honda civic, 1.6 base model. The change over went well and had no problems. When I have the car idle and it gets up to temp, the RPM's go from 2000 down to 500 then jumps to 2000 then down 500 again. When I put it into gear, drive or reverse, it stops jumping. What did I do wrong?
View 4 RepliesMy car has been having idling issues for about a year now. While idling the RPMs oscillate between 1 krpm and almost 0, with a frequency of about one oscillation per second. That got worse over time, and it started dying while idling too. I ignored the problem because it wasn't that bad, until a few weeks ago it died about 7 times on a 2 mile trip. (I developed a technique of using my right foot to press the gas and the brake simultaneously so I could come to a stop while keeping the engine going. But that only gets you so far.) I took it to a garage, they said I probably need a new IACV. Instead of having them do it, I just bought one and put it in myself. I'm not an experienced mechanic, but this seemed fairly easy; I'm pretty sure I didn't screw it up.
So, now it's displaying almost the exact same symptoms. It's not oscillating like it was before, but it's still dying pretty frequently, only on idle. I'd like to know if there's anything else I can try before I take it back to the shop.
A little more information about my car:- Replaced the motor about a year and half ago, put a few thousand miles since then. I don't know what other parts were replaced as part of the motor, but probably not many considering what I've had to replace. - Since the motor replacement, I've had the following replaced: rear main seal, clutch, distributor, distributor again, and water pump- The odometer reads 223k miles, but I don't know how many miles the new motor has. - 1990 Honda Civic LX 1.5L
I am desperately seeking info about my 1998 Honda Civic. My engine keeps quitting on me when I am either stopped at a stop light idling or the rpm's are really low. This seems to happen at random with no warning or check engine light. I keep my tank more than half full with gas so I don't believe this could be it. I have been to my mechanic and they said it could be a multitude of things wrong with it so it doesn't make sense to put money into the car if it won't necessarily fix it. I am desperate to figure something out so it can get fixed because I have to drive to work everyday and I'm sick of feeling anxious while driving all the time!
View 5 RepliesI have a 2012 Honda Accord EX with a manual trans. It's a fly-by-wire system. When accelerating and shifting, the tac momentarily jumps various hundreds of RPMs when the clutch is in. That used to mean you weren't coming off the gas when the clutch was in. I've been driving manual trans cars for 45 years. I know how to shift. But, it was a new car, so maybe... I paid close attention and was not screwing up the shifts. Apparently the computer doesn't realize the clutch is in and the gas pedal has been released. Is this normal for these cars? Is it a problem? (other than wasting a half thimble full of gas and over-reving the engine?)
View 4 RepliesI have a terrible car. Honda Civic 2002 that runs alright but quakes and shudders after I start it. It also revs up for no reason at all whilst I drive around. Anyway two machanics have told me I have a headgasket leak that will cost a lot of money to fix. Two others have told me I don't or that it is so minor it needs not be messed with. The last one I saw decided I had a bad Coolant Sensor for the Computer.
I guess there is one for the computer and one, um, not for the computer. I bought both sensors and he changed them Friday. Today I took the car out and three times while I was out, my temp gauge shot up into the red hovered for a few minutes and sank back down. It has never done this before. Why this might be happening now? I am really sick of taking my car in and getting a thousand different stories, paying to fix things that are not wrong with it and watching it die a slow death.
I have a 98 honda civic ex with the d16y8, have replaced the map sensor and iacv and still have a fluctuating idle only when car is warm or at operating temperature. it has dc sports racing headers into a straight pipe then exhaust tip. does not have any o2 seniors on it(wasn't my choice was like that when i got it) will idle up and down between 1700 and 2200 rpm also after replacing iacv the car jerk when going at low speeds or letting off then getting back on accelerator.
View 19 RepliesI drive a 2002 Honda Civic EX with about 105,000 glorious miles on it. I decided to hit the road and made a weekend road trip to pick up a stranded family member. I live in Ohio and drove Lou Dobbs, my car, to Florida. It was about 950 miles one way. All was well until I got to Florida. I hit my first traffic jam and was sitting with the windows down enjoying the Florida air. Suddenly, the temperature gauge started to climb! It got pretty close to the red but traffic began to flow at that point. As soon as I reached 40-50MPH the temp began to fall again. I picked up my cargo and headed back. Each time I would hit traffic or a red light the temp would climb without hesitation. This is without the A/C running. After I got back to Ohio, i asked a friend who knows about cars. Over the phone, he had me remove the radiator cap and reservoir cap to take a look at the fluid levels. After this though, the car has never overheated! I don't understand. Can air get into the system and I let it out by removing the caps? I can sit in rush hour traffic for a half an hour with the AC running and the needle stays right in the middle. Should I still take it in to be looked at?
View 2 RepliesI have a 2004 Honda Civic that has about 183,000 miles.The problem is that when I start my car in the morning, the car never totally warms up when it's cold outside (I live in VA), until I press the gas pedal and rev the engine. Until I press the gas pedal, the temperature gauge stays at cold, and the heater blows cool air. I've taken it to the dealer 12 times for the same issue, but they can never find the real problem.
They flushed the A/C hoses and radiator, replaced the radiator cap, installed an upper hose, installed head gasket, water pump, and while there, the timing belt. They've also "burped" it numerous times. Also, when I have the heater on and fan on high, the temperature gauge drops as I'm going down a mountain and not pressing the gas pedal. After driving, and I stop, it also slowly drops while idling for about 5 - 10 min.
When it's warmer outside, I don't have any problems, because I don't have the heater on. This has been going on for about 1 1/2 years now, and it's starting to get cooler again, so I need to get it fixed or sell it.
Noticed my beater Honda del Sol (177k miles) idling slowly the other day. Normal 45F day, light urban driving. Usually idle is ~800rpm (indicated), was dropping to 600rpm and even 500rpm. Holding her at 1000rpm then releasing the gas pedal yielded ~300rpm and it almost died, followed by ~500rpm. Ran fine at any other speed; it had no hesitation, no noises, and no warning lights.
So my GF said, "you're probably low on oil; my Cooper S did that once". Huh? Why would low oil, other than if it were so low that it starved the engine and caused friction, impact the idle? If anything, I'd think it would idle faster with less fluid to pump, and/or with hotter and hence thinner oil (assuming it'll run hotter if it has less oil, which it didn't appear to be).
Sure enough, I checked and it was about a quart low. I've never had a car that uses oil, plus my cars usually have oil pressure & oil level indicators (i.e. Porsche 944S2). So I've never run those lower than near the bottom of the "normal" range.
Searching "The Google" only provided unsatisfactory answers about metal-to-metal grinding and galling slowing down the engine, which is not what is happening here. There is still oil pressure, the oil light does not come on, and the engine sounds "normal". And adding oil immediately cured the slow idle.
I have had my 1998 Honda Civic for about 5 years now... I bought it used. Occasionally I have noticed my oil levels have been low every 2 months or so. Oil is not being burned and doesn't leak. It hasn't affected performance from what I can tell. I have basically monitored the levels and everything has been fine. There was also an electrical issue since I have had it.
About 8 or 9 months ago, I noticed the temperature gauge was basically in the red while driving. I pulled over and noticed the oil was reading empty. I put oil in it and took it to the shop the next day. They told me the head gasket was bad and that the oil and coolant were mixing and recommended I replace the engine. I asked them how long I could manage before the car quit entirely and he said maybe a month, two if I kept doing oil changes.
I put the heat on while driving it, and the temp was normal. I took it to another shop the same week. They couldn't get it to overheat for a couple hours. The guy told me it was probably the fan but wouldn't know unless he could see it overheat. He said the fan would cause it to overheat at stoplights when there wasn't air on the engine. When the car gets hot, it doesn't get worse at stoplights and is only after I've been driving like 20 minutes that it heats up. I asked that he call me as soon as he knew what it was and I would decide whether I wanted it fixed that day or not. Then I didn't get a call for awhile, and when I called them, they said the guy was out getting the part. I felt like they were rushing so I would replace the fan. I asked if it was the head gasket because I didn't want to fix a fan if the engine needed to be replaced. They said it was not. I didn't replace the fan. They also told my husband that we could save wear and tear on the engine by putting the air conditioning on instead of the heater. When we do this, it overheats. Its only when the heater is on that the temp stays normal.
I have been driving the car for 8 or 9 months now with the heater on with no performance issues. It doesn't overheat and even when I forget to put the heat on it goes up to the red, but doesn't "overheat" with the steam and whatnot. It doesn't seem to do anything to affect the performance of the car. We have replaced the radiator cap, which had pieces falling off, and it didn't work. The check engine light came on yesterday and the code indicated something to do with the transmission.
We took it to a third mechanic today and he said I needed a new thermostat... I do not see any sort of film in the oil. We just flushed the coolant today and there was no sign of oil. I'm totally lost on what to do. I feel like the mechanics have lied to me about what was going on. They contradict each other and the little things they told me don't seem to be the case or don't work.
My 2005 Honda Civic has just started doling out heat when it feels like it regardless of where I set the dial. It seem that when I am accelerating or applying gas, heat is available but when I am stopped at a light or coasting downhill, cold air is all that is available. Is this a thermostat issue or something more dire?
View 1 RepliesThis weekend I was one a trip in my '98 Civic, and I noticed some movement in my temperature gauge. It didn't really overheat; the needle never got near the red, but it did go a little higher than usual.
Normally, once the engine heats up, the needle on the temperature gauge doesn't move, not even a little. It sits right under the squiggly lines on the temperature gauge icon. However, on Friday, when I got off the highway, the needle rose into the upper part of the icon, to the part with the thermometer.
As soon as the car started moving, the needle on the temperature gauge went back to its normal spot, so I assumed it was a problem with the radiator fan and I kept on driving, prepared to turn on the heat if the needle on the temperature gauge started going up.
Saturday morning I took the car to a local shop in Jacksonville, and it turns out the engine needed a new fan and a new thermostat.
The first lesson that comes to mind is that keeping an eye on my temp gauge might have saved me an engine. It certainly saved me a head gasket. Since a head gasket or new engine would have been worth more than the car, catching this before it became a problem saved me from having to buy another car.
The next lesson is that my Civic had two things wrong with the cooling system, and yet it barely showed any symptoms. The air conditioner doesn't work I guess since a working A/C would probably have made it overheat. In any case, I've probably been driving without a working radiator fan for some time.
The final lesson is that if I had tried to diagnose this myself, I'd probably be driving around with a new radiator fan and a bad thermostat. I paid about $435 for a new fan, thermostat, and fresh coolant (I declined the cooling system flush) and it was worth every penny.
The car I drive is a 1997 Civic EX, and if I drive it for about five minutes, the temperature gauge starts creeping up real fast. It'll go to the red if I let it, and the only thing that brings it down is turning on the heater and fan, at full blast. which is pretty miserable in summer.
I looked under the hood and found the radiator fan isn't starting up, no matter how hot it gets. So I checked the fuse - it looked good. Replaced it anyway just to be sure. No change. Then I replaced the relay switch. that didn't change anything. And I also replaced the fan motor. Still nothing.
I have read elsewhere that I should check my thermostat, but I can't see what it has to do with the fan motor not starting? also that the Engine Coolant Temperature sensor might be faulty but it is my understanding that that controls fuel-air mixtures and I just don't know.
Thinking of buying a new civic with mt. One annoying thing is many mt rev higher at speed than automatics.
Tried to find out online how high civic revs, couldn't find it though.
I'm thinking anything over 2500 is going to sound whiny on a long trip.
My 03 civic will drive fine when the engine is cool. But after getting off the highway, or running it at higher speeds, when I put it in gear, any gear, it will start choking and bucking like its running out of gas. Once I get it above about 2000 rpms, the choking stops. The read out said it was the egr valve at first, we had it cleaned, but it didn't fix it. The readout now says recirculation insufficient or something like that. I'm wondering how serious this is, and if I should be driving it.
View 5 Replies1998 Honda Civic EX. This has been a great car and have got a ton of good miles on it. The problem that I am having now is with the temperature gauge. The measurement is completely all over the place while driving. While moving around town, the gauge shows the temperature VERY hot. As soon as I reach a consistent speed, the temperature drops back to normal (moves very erratically!). The gauge seems to get even hotter while idling. Another issue (may or may not be related) is the heat coming out of the vents is only working while the car is in motion. While stopped, it pumps out cold air. The temperature immediately changes when I get going again. Both problems seem to be getting worse. The car has coolant, and all other levels of fluids are normal.
View 14 RepliesRPM's will not get above 2000, in 1st and 2nd gear. No power....
View 16 RepliesMy 1998 Honda Civic DX's RPMs are fluctuating during idle. I start the car and it is normal for about two seconds. I am assuming around 800 rpms (I don't have a tachometer). Then it jumps drastically higher, then lower, then higher, etc. Earlier tonight I replaced the throttle body gasket, replaced the spark plug wires, and cleaned the fuel injector cleaners. I took off several things in the process. I think the problem originates from taking apart the throttle body - not the other replaced parts. I have a manual 2-door 1998 Honda Civic DX with a 1.6L engine (D16Y7 engine to be exact).
View 15 RepliesIn the Car Talk column on 1/3/2016, it sounds like Lynnette's 1991 Honda Civic wagon was experiencing very similar symptoms to my wife's 2001 Honda Odyssey (189,000 mi) a few months ago. Rough idle, engine almost dies sometimes at stops, groans during acceleration. Additionally, accelerating between 40-60 mph our Honda would feel like it was "loading up," running rich or in the wrong gear climbing hills. I replaced the idle air control valve, which fixed the rough idle but not the other symptoms. Turned out I needed to reset (power cycle) the ECM and go through a curb idle/rev warm-up procedure so it would relearn the throttle position sensor's operating range after replacing the IAC valve. I disconnected the battery, removed and reinserted the hazard fuse, then reconnected the battery. Then from a cold start held the throttle at 3000 rpm until the engine warmed up to normal or the electric fans kicked on. Since then it's back to smooth, strong acceleration we expect from the Honda we love.
View 1 RepliesI've had my 2000 Honda Accord V6 for about 3 years now and have had an idling issue pretty much since I purchased it. After driving for at least 50+ miles, and if its hot out it can easily have this issue as well, and leaving the car be for around 15 to 30 minutes, on start up the car drops RPMs immediately and dies. Multiple tries and it will do the exact same thing. Recently I found out a trick to make it work correctly which is revving the engine to 2000RPM for about 3-4 minutes, slowly dropping it down to 1500 RMP for around the same 3-4 minutes and finally down to 1000 RPM for an additional 3-4 minutes and letting off the gas. Usually after doing this the engine idles fine, car drives great. However, it must be noted that on Summer days with temperatures in the 85+ range, if I'm climbing (going up a hill for a long distance) the car might bog down on me, will not go above 50MPH and I have to pull off the side of the road for 45+ minutes before the car will run correctly again. This has happened about 3 or 4 times in the 3 years I've owned the car.
I would rather not have to rev the engine in hopes this fixes the issue each time so I'm wondering what could be the cause in the first place? I've replaced so many things including spark plugs, ignition coils, battery, idle air control valve, gasket, fuel pump, fuel pump relay and on. I gas the car up with Chevron gasoline, I've dumped in I don't know how many different fuel injector cleaners and have also tried Heet as well as Sea Foam cleaner. I've also had the car checked for vacuum leaks.
I've asked multiple mechanics if this could possibly be a vapor lock issue, but they all turn that idea down. They tell me that since the car is fuel injected this can't be the issue..but, I don't know, could it be the issue?
I have a '03 Civic DX 5 speed. It has 128000 miles on it. I've notice now that it is getting colder, my engine ticks when it is warm - I can hear it at idle and low rpms, but not at higher rpms. It sounds perfect when it's cold, but once it is warm, it has a "tic-a-tic-a-tic-a-tica..." sound. Tom and Ray talked about a Dodge Dakota that made the same sound when the engine was cold (about 8 episodes ago). So what does it mean if it only does it when warm?
