My 2000 Honda CRV with 200K miles has a repetitious knock only when idling with the AC on, apparently the compressor clutch engaging and disengaging. The AC is cooling OK. I've had the compressor, dryer, and expansion valve replaced - twice - and the same knock continues.
View 1 RepliesI have an intermittent knock under the hood, only when idling at a light etc. One mechanic replaced the AC compressor, expansion valve, etc - still a knock. They put in a second new compressor - still knocking. A second mechanic replaced the expansion valve - still knocking. Air conditioner has worked fine from the start.
View 1 RepliesLast week I got back from a two week trip and came to turn on my car (95k miles) and I quickly noted a flat. Put the car in park to check it, and all of the sudden the engine is revving--1500rpm up to about 3500rpm and back down, over and over again. Put on my spare and headed to the shop. The whole way there, about four miles or so one-way, the car could hit 40mph without me on the gas. I turned the car on/off about five times, still having the same issue. In total, I drove about 25 miles with this issue, then, all of the sudden it seemed to be solved.
My mechanic seemed troubled by it when he took a look. No one could diagnose the issue, just had the air leak that caused the flat on a Saturday afternoon fixed, but I haven't taken it back to them because the issue isn't happening anymore.
This comes on the heels of taking it in and having the fuel relay fixed because of the well-documented issue with this car stalling on start with warm temperatures. That fix was supposed to take care of things, but the issue still persisted following the fix.
2000 Honda Accord EX V6 Coupe....
I'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?
Our 2003 Honda Pilot with 130K miles recently developed a front end Knock/rattle, which is sustained at about 70 miles per hour. Dealer "couldn't hear the noise". Tried new tires per dealer suggestion- fail! Recently we towed our 2100 lb pop up with it, and it was MUCH louder, and of course sustained at lower speed. Should we even be towing a pop up with a vehicle that has this many miles on it?
View 2 RepliesMy 2013 Accord V6 EX-L with 5,000 miles emits a strange sound, under certain circumstances. The sound is hard to describe but reminds me of the old days when your engine would "ping" or "knock" if you used gas with too little octane. Of course, the current Accord only requires regular gas. At any rate when cruising between about 45 and 60 MPH, if you push on the accelerator (not enough to cause a downshift) and especially if on a small incline, you hear a very distinct knocking or rattling sound. Over the past 6 months, the sound seems to become more frequent and noticeable.
I have been to the dealer and the service manager drove the car and agrees he hears the sound. But after consulting with Honda engineering they concluded it is "characteristic" of this engine. They say it emanates from the "paddles" (??) within the automatic transmission vibrating or rattling. After being told that, I drove 2 other 2013 V6 Accords on their lot, and they both made the same sound. My question is, do any other owners notice this? I find it very distracting and also disappointing after paying so much for a new vehicle only to own something that strikes me as deficient.
How can Honda produce and distribute a vehicle with this annoying and obtrusive characteristic? It is hard to believe they did not catch this and fix it during product development. I even drove a 2014 V6 Accord last week and could just make out the beginnings of this same sound, so apparently it was not engineered out for 2014. This makes me lose confidence in long term ownership of the vehicle as well as fearful of potential future transmission problems.
My cousin has a 2011 honda civic ex A/T and when he lets off the gas his transmission makes a quick knock noise. It's not too loud but it's very noticeable. Shifts fine and everything. Also it sounds like he is forcing his transmission from park to reverse. We hear a lot of noises not so much grinding noises but a lot of movement I guess you could say. But it engages quick. Is this normal or should we take it in? I have had multiple people tell me it's all normal. But it doesn't sound normal to me.
View 4 RepliesWhen ever I hit a bump, the front passenger side around the front wheel area rattles but doesn't when i brake, could that be covered under the 10 yr? Our car only has around 36,000 miles on it .
View 1 RepliesI have a 2000 VR6 M6. I will do my best to describe the problem I am having and what I have done so far.
I get a knock when going in to 1st, 2nd or reverse. If I let the clutch out real easy I will not get it. If I go in to 1st depress the clutch and then move forward again it is not there. Same with reverse, go in to reverse and I get it but depress the clutch and then let it out it does not happen. When going from 1st to second during normal diving I will get it, and leaving from second I get it also.
What I have done and looked at so far, replaced the left side mount and the dog bone. Inspected all other items such as the control arms, body mounts and stabilizer bar. I have also changed the fluid with Synthetic 75w90. Axles look pretty good and I do not suspect it is there.
Since of lately my 2001 santa fe with about 143000 Km on the clock is having a ignition knock when the RPM is about 1500-2000, also changing to 2nd gear (Auto Box). What it could be and how to rectify it?
View 2 RepliesMy Honda Fit has had this problem for over a year; I've brought it in to multiple shops and they couldn't replicate it. I first thought it only was happening when the a/c was on, but now that it's winter, and the heat is on, it seems to be occurring all the time. The car will "jump" (bump?) when idling, and will now (newly) do the same thing while driving. I can't identify what it might be and when I bring it to the shop, it decides not to do it when they test drive.
View 5 RepliesThis is a 2000 EX with 146k miles on it bone stock. I have not done any of the regular maintenance on it yet or even gotten to really check this problem out. I am not driving it at this time mainly due to this problem.
The noise is heard the best at the rear of the engine and underneath the truck as the video shows. It seems to slightly change in sound (maybe a tad bit quieter) once I put it in gear (drive and reverse), I have not really heard a change in it after the truck has warmed up either. It does not sound at all really metallic to me..

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.
My 2008, standard transmission, Honda Element just turned over 100,000 miles recently. Over a year ago the engine started making a "hurrr hurrr hurrr hurrr hurrr" noise and shaking the whole car while I'm sitting at a light or stop sign without touching the gas pedal. If I turn the air on it will stop, but starts up again if I turn the air back off. It doesn't do it all the time, and of course didn't do it when I took it to a mechanic to have it checked out in June. They hooked it up to check for engine codes, and got nothing, so they weren't really sure what to fix since they couldn't make the engine do what I was describing. They did bring a whining noise the engine is making to my attention, and suggested replacing the alternator and 2 associated belts in the engine. While they were in there fixing things, they noticed the lubrication looked contaminated - like water had somehow gotten inside - but couldn't say how.
Unfortunately, my car is pretty much right where it was before visiting the mechanic - only now I notice the constant whining that gets louder when I press the gas pedal, as well as the occasional shaking and "hurrr hurrr hurrr hurrr hurrr." People who ride with me notice the whining too, and whenever the engine starts shaking they think I should have it looked at. to which I reply, "yes, I have. fat lot of good it did me."
I have upgraded my sound system in my car and sometimes i get a P0326 check engine light.
Now i was wondering if its possible that the Heavy bass ( 25/40 Hz, 1200 Watt RMS and 2500 watt Max) Subwoofers could cause the car to vibrate so much that it sets of the knock sensor?
I have read some things about it but i only found that several "Old" cars with OBDII would have this problem? Is that the same on this hyundai accent?
It only comes once in a while after long cruises and bumping.
My V10 was knocking when accelerating under 2000 rpm; rain and moisture made the problem worse. I discovered that the 2-part wiper cowl under the windshield allowed water to leak into the engine compartment and onto the throttle body, which then dripped onto the left side of the engine. This caused the spark plugs to rust and the 3 back ignition coils (coil on plug) on the driver's side to crack and fail. This caused a horrible misfire/knock that was worst under 2000 rpm especially in high gear and when the environment was wet. I fixed the misfire and cowling leak. Has not returned. I caulked the cowl and changed all my spark plugs and ignition coils.
View 3 Replies When it is cold outside and I want to turn my heat on in my car, it takes a loooong while for heat to be produced. I have to have the car moving at a high rate of speed before any heat is made. Even when it is turned all the way to the hottest setting it just spits out cold air. Here is the real problem. If I have the temperature on the heat and the car is idle, the temperature gauge on the instrument panel starts to move around to the RED side(meaning the engine is hot, right?)
As long as the car is moving the gauge will stay in the BLUE(engine is cool, right?) As soon as I stop the car at a red light or sit in traffic(which is usually the case) sure enough the little temperature needle begins to make its way to the RED side. As soon as I move again, it normals again. I have taken this to several mechanics and they have said that they do not know what is wrong and they think that it may just be a faulty temp gauge(this does not seem right) I do not really know if the car is in fact overheating when the gauge starts its travels or if the car is fine and I just have something that is faulty.
We have a newly acquired Honda wagon, 16 valve, PGM FI, auto trans, that revs while idling. It sometimes does it when cold buy also hot. It increases it's idle to 1500 and drops revs to 1100 about every 6 seconds. Normal idle seems high at 110.
View 3 RepliesI have an older 2001 Honda accord I4 about 160k miles on it. I recently noticed that there's a rattling sound when the car in in idle (800RPM) but it disappear when I rev it up to higher RPM or while driving. The noise can't be heard inside the cabin and can only heard outside. The noise also only appears when it is warmed (engine running for about 3 - 5 minutes after cold start). I read from other board about a loose or worn out heat shield so I went under the car and try to look for a loose of broken parts but I cant find any. I removed the cat heat shield but the problem still exist. I don't know what else to check. Car seems run normal, I don't notice any change in performance and no check engine or what so ever. I just wan't to make sure it is not something on the engine, transmission, or something that will snowball to a bigger issues. I don't know how long its been rattling but I just noticed it the other day.
View 11 RepliesI 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 RepliesThe truck starts fine and when it was idling just started this loud machine gun sound for a few seconds, then stopped, and then happened again. I turned it off, and now...? May or may not be related but the battery was dead yesterday. We jumped it quickly and drove it to let it charge. Had the battery checked and it tested good. The battery is only about 6 months old but it's been pretty hot here in southern NM so figured that was probably the cause. There was no check engine light. I did a search here and spark plugs were mentioned for a Ford, but not sure if that holds true for the Honda.
