Civic - Honda :: 1998 - RPMs Fluctuate At Idle
Feb 11, 2011
My 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).

,My '98 Honda Civic EX (manual 5-speed) is currently at 200,000 miles and makes a gargling/metallic rattling noise when I accelerate from low RPMs or whenever I'm climbing a hill. The noise sounds as if loose change is rattling around somewhere in the engine. I started noticing this a few years ago, when it was very slight and it only happened in second gear as I climbed a steep hill.
Over time, it started happening in third and fourth gear, and now it is in all gears when climbing a hill or when accelerating quickly on level ground. I also notice a lack of power when this noise is occurring. In the past, if I let off the accelerator just a little bit, or if I greatly increased on the gas, the noise would disappear. Now, increasing on the gas makes the sound worse.

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?

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.

1995 Honda EX with 150,000 miles. Its been running rough ie rough idle, stalling at low rpms etc Additionally for awhile now when humidy reached north of 85% the car wont start. It cranks but rarely runs.
Took it to a mechanic last week for a tuneup. They replaced the Distributor cap, spark plug and wires and fuel filter. Car ran great for a day. Then progressively got worse. Was undriveable the other day stalling misfiring while at speed. Took it back today. They determined that it was still not getting spark and replaced the distributor. They did so, test drove it, declared it good and I came to pick it up. Paid the bill, walked out to the car and the damn thing would not start. Humidity was high.
Mechanic pulled a spark plug and put a tester in and didn't get a spark when cranking. He is assuming the distributor he just put in is bad. So they are keeping the car overnight to be fixed in the morning with a new distributor.
However I'm not convinced the dizzy is bad, I believe, as I've read that the Honda's ECU is probably bad and shorting out in the high humidity. Can a bad ECU would prevent spark?

So I have a 2.0 jetta and I'm having this problem where my rpms fluctuate at idle and sometimes the car dies unless I give it gas.but when I'm driving if I'm not in gear and stop it sometimes dies.
I'm getting 5 codes : P0445, P0135, P0037, P0418, P1473
I checked all my grounds I changed the 02 sensor on the manifold checked for cut wires and nothing ...

After I got done with all of this crap on my Ranger, I noticed that it was driving great! But...today I was on my way to school and BAM! My engine idle started hitting (presumably because I do not have a tachometer) about 3000RPM and lowering down to about 2500RPM and from there, every time I am not in gear it decided to fluctuate between 2500RPM and 3000RPM. Crazy style too.
Now, I got to school, and getting closer to it at a stop light the truck basically died. It was almost at 100'ish RPM. I gave it gas, and BAM. I hear a continuous hissing noise from under my hood. Haven't diagnosed it fully yet because I just got home and its 12AM.
Now, every time I stop at a light or in traffic or whatever it may be, I have to give it gas every other second, like a small push on the pedal, to make sure the truck doesn't die. Also, every time I am out of gear and my RPM's are at an 'idle' state, I get continuous hissing from somewhere, I get no power loss or anything, just really weird idle RPM's and hissing when my foot is not on the gas basically. It is strange. I think It is some sort of Vacuum leak but I am not sure.
To get a better picture of the 'hissing' noise, it is the same hissing as you would hear when letting the air out of a tire. That is the best way I could describe it.

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.

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?

My 1998 Honda Civic has been dormant in my drive way for about a month and a half with very little gas. I went out to try to start it the other day and it struggled for a bit and never turned over. It isn't the batter considering the headlights and radio work just fine, thus I sought out the nearby gas station and attempted to solve the problem by putting gas in it, yet when I returned and emptied out my gas can into the tank it was the same ol' story. What it could be?

My 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 have a 1998 honda civic LX that slips very very seldom upon acceleration. It happens under light acceleration and medium acceleration (I dont accelerate hard enough to see it slip at high acceleration, it might!)
What happens is, the car stops accelerating and simply idles. As the motor idles the car drifts and slows down. I have never done it, but I bet in this state I could come to a complete stop just by drifting if I keep my foot in the same spot on the accelerator. When I change my foot, and accelerate harder, the car wakes back up and keeps accelerating like nothing even happened.
I don't think it is the transmission slipping, because in that instance revs would climb and acceleration would halt and that is not the case. I recently gave the car a huge tune up, here's the list
Valve adjustment
Oil and filter change
Cleaned throttle body and IAC
New distributor and cap (Plug wires aren't really in good shape)
New spark plugs
New air filter
Set the timing
New belts
Cleaned injectors
Cleaned battery terminals
I don't know what could cause this problem! The only thing I have come up is the Possibility a TPS (Throttle position sensor) going bad. The only thing that I know of that is wrong with the car is the exhaust manifold has a big crack in it right before the upstream 02 sensor. No doubt this leak is messing with the cars readings of the AFRs. Could this be part of the problem? It is throwing a code for the catalyst system.

I've been checking my oil every morning for a few weeks now because of a worry about it burning off. I check it at the same time each morning, in pretty much the same parking spot, before driving it. Every time I take out the dipstick, wipe it off and put it back in to check. What's weird is that the level seems to fluctuate. Some days it's up over the higher dot. Some days it's down closer to the lower one (though it hasn't been under). Most days it's somewhere closer to the middle between the two. Is it common for it to fluctuate that much on a day to day basis? Is it something I should be worrying about?
In case it matters, it's a 1998 Honda Civic LX.

I have an issue with my 98 honda civic lx, with 197000 mils. Recently I had my Check engine light on. I ignored it for a day. The next day started my car and in the middle of the road it stopped moving, meaning in spite of accelerating it doesn't move. So I stopped at the shoulder, turned off the engine. After a while I started again, the car moved but later on it stopped moving when I was accelerating. The Engine did not turn off during the stall. Couple of weeks back the car was shaking on the front side when I was driving, it felt like the car was about to stop as if it was short of fuel.I changed the spark plug 15000 miles back. Water pump and timing belt was changed 25000 miles back.Car has a highway mileage of 32 mpg.

My 1998 Honda Civic has oil in the radiator. And even stranger, the oil winds up in the overflow coolant reservoir. What is the most likely cause of this?

My 98 Civic ex runs and shifts perfect to have 200,000+ miles but when you try and shift to reverse it grinds. It acts like it's gonna shift into reverse but doesn't. When you shift back into park or neutral you can hear it still spinning. Sounds like a card in spoke of bike. We have drained fluid twice and replaced also added trans-x.

I've got a 1988 Honda Civic Sedan. 151, 000 miles. Runs great,except when I have to stop for gas or I pop the clutch maladroitly to get going and kill the engine. Then it won't start up. It used to do it once or so every five times I stop to gas up. I don't drive it much and have to re-charge the battery every month or so--even the new battery. It started this herky-jerky thing last summer but the tow guy convinced me it was a bad gas problem. A gas additive seemed to clear it up, but not the starting problem.
Just last night I recharged the battery,let the engine run 15 minutes or so the next morning, then shut it down and tried to restart it; turned over but wouldn't start. In general, when it cools down about an hour or so later, it starts fine. So engine heat seems to cause it.I've giving up trying to gas up at the cheap stations. Instead I go to the local station two blocks away so I can push it aside and come back later to get it if it stalls. Could this be something simple I could fix?
