Honda - Cr-v :: 2000 - Idle Surge That Just Won't Quit
Aug 26, 2011
have a 2000 Honda CR-V with a B20Z2 engine and automatic tranny. This Honda has an idle surge that just won't quit!! (surge= rpms rise and fall, repeat) It's really driving me nuts and I need this car to drive for school next week! So far, I've:
-cleaned throttle body
-replaced spark plug wires (plugs are fairly new), distributor rotor, and distributor cap
-bleed coolant
-ECU relearn idle
-adjusted intake and exhaust valves (tight exhaust valves are incredibly common on my engine)
-cleaned out Idle Air Control Valve with Simple Green
-performed vacuum test (with propane, not carb cleaner since it works the same)
-performed compression test (every cylinder checked out)
-replaced throttle body gasket
I've had Check Engine Light misfire codes for a while now, but they pretty much disappeared after the valve job. All that's left is an Idle Air Control System code (P0505). I'm am completely stumped at what to do now. What's more is that white smoke has started pouring out of the tailpipe and it doesn't smell like coolant. At first I thought it was the oil in the cylinders from the compression test, but now I'm not sure. It doesn't really smell like oil or coolant, but it smells like something is burning....

I recently purchased a 2000 Durango with 151K on the clock. It looks like it was well taken care of, clean inside and out, and runs/drives nice. I just have 2 "concerns". There are times when the vehicles shifts from 1-2 and 2-3 it "shudders", only does it for a split second, and seems mainly when pulling out on some sort of upgrade, but not always. Otherwise it runs and shifts fine.
The second "concern" is that it seems to surge a little at idle. At a warm idle in park is when I noticed it. It goes from about 750 rpm to 950 rpm over and over. I haven't really noticed if it does it during regular driving.

My 1992 Toyota, Celica had developed a really weird idle surge. The idle surges between 500 to 750 rpm. The surge goes away with the AC on and it idles steady at 900 Rpm. It also has a slight off idle bog that may just be another symptom of the weird idle.
I did the diagnostic test today and it doesn't flash any codes. I pulled the EGR valve off and cleaned the gunk out of it and it didn't make any difference. I tried to check the timing and it idles so bad the timing bounces 7-10 degrees with the surge. When I did the jumper to check the timing it would kill the engine. The plugs and wires are new with in a couple thousand miles. It runs fine above idle and pulls to redline easily in the lower gears.
Yesterday when I was messing with it I had the car running with the air boot from the air cleaner to throttle body off. I sprayed carb cleaner into throttle body and it seems to clear up a little bit. Then it went back to surging again.
I tried to pull the TPS off yesterday and of course the bottom screw stripped out. Now I will have to pull the throttle body off to get the screw out. I wish it would throw a code so I could have it give me a clue.

My 90 lumina euro 3.1 has idle surge after it warms up. fluctuates between 600 and 1200 rpm when in drive. When you first get on the throttle it wants to die. Once you get past that it runs smooth while driving. Ive also notice that it tries to "buck" when its at lower rpm and barely on the throttle while pulling.
I can't seem to find any vacuum leaks, has recient tuneup, had a egr code and that has been replaced. I've cleaned the throttle body also. Previous owner had intake gaskets replaced as well as fuel injectors, fuel rail, fuel pump.

My truck has been having idle surge, low engine power, says stable tracks is off, computer said TPS pedal sensor. I replaced it. Within 3-4 days my truck does the same thing. I turn it off and eventually my truck runs fine with the exception of my engine light is on truck runs good. I put the computer on it again while the truck running bad and it continues to say it is the TPS sensor.

Just purchased a 99 passat v6 and it has a low idle surge and stalls when coming to a stop.It runs fine until it heats up about 15 min. then it surges up and down and stalls.

I have a 2008 Hyundai Santa Fe. Has about 65k miles on it and has regular maintenance and tune ups when needed. It is cared for. The last tune up was about 2k miles ago. Spark plug change, oil change, filters, etc.
I have noticed lately that when the car is moving at idle speeds, it will surge about 200 rpms. It does not happen when the breaks are on or stopped or in park, or moving at higher speeds. It only does it while moving and with no acceleration. It happens in Drive and Reverse.
I live in the city of Lima Peru so a 4x4 is useful but it also requires some tight parking but when it starts to surge, it is a huge pain.

On startup, hot or cold, I get an initial high idle, up to around 1800 rpm's. This happens immediately when engine starts, and then idles right down. This has done this since new in '04. Dealer at that time said it was normal and not to worry. It's always made me wonder, but I trusted the dealer. Ya, not always smart.
After 92k miles. Engine runs fine otherwise, but I don't really care for grabbing a bunch of rpm's on any engine without having the oil pressure up to normal.
A few weeks ago, I started it up, and some yahoo said he knew I drove big trucks by the way I started my Ranger. That was one of those times. I'm thinking IAC is wide open maybe?

I have a 2003 silverado with a 4.8 engine. i bought the truck in the summer of 2010. no problems in the winter of 2010. ran great all year in 2011, then my block heater shorted out in the winter of 2011, so i wasn't able to plug the truck in.
We get some cold nights up her in alberta, but anything below -10c the truck would idle surge and stall, would do this about 4 times in a row then it would just surge a few times but stay running.
I had a buddy that's a gm drive ability tech take the truck and do a tone of updates for the throttle body and to correct idle surge and some other drive ability related stuff. i cleaned the maf, map and tps as well as the throttle plates. replaced plugs, wires, air filter and fuel filter. all this and it was still doing it, but it had to be really cold to stall.
wasn't able to replace the block heater till this summer. but now that its getting colder and dropping below -10c at night the truck is starting to idle surge when i start it up in the morning.

The title pretty much explains it. Coming home today started hearing a squeal/whistle while at highway speed - almost sounds like the brake wear indicator tabs that GM is so fond of. Thought it might be the brakes, but it didn't stop with brake application and continued after coming to a full stop. Also, surging at idle, which seems to be reduced when the A/C compressor is on. The squeal happens both with and without A/C.

My 2009 with the 3.3 motor will rev up when cold drop to a low idle then surge up again. It will do this until it is warm even when in drive. It never did this before only in the winter it would start at fast idle for a minute then drop to normal idle. There are no codes or lights, what would cause this?

While driving on the freeway my car started to surge as if it was starving in fuel. I had to press more gas to go the same speed. My gas tank was at a 1/4 full so I pulled into the gas station to fill in gas. As I was leaving my car could not accelerate while pressing the gas pedal. I could floor the gas and it would go only five miles an hour! The engine temp was okay, no engine lights, and no weird smells. I was fortunate to be close to home and slowly made it letting cars pass me on the side. I called the road side service who towed my car to my dealer. They checked for codes, ran fuel injector cleaner twice through the system, checked the fuel pump, and the pressure on the fuel system, no problems. The third day they gave me a Sonata for a loaner and I allowed the service manager to drive my car to see if the problem reappeared. No problems found and I picked up my car today. The problem hasn't reappeared yet but I am keeping track of any rough acceleration or idle.

91 olds cutlas supreme with about 70,000 miles has a miss - when cold runs fine warms up then does not want to idle and has a surge feeling but at highway speed do not notice it. Plugs are clean, spark wires changed 8,000 miles back . Could it be a coil pack failing?

The ac condenser unit will click every 7 seconds followed by a 3 to 400 rpm surge for 5 seconds or so, drop rpm then repeat. Belt looks fine, no slipping, new plugs a month ago, newish air and gas filter, does it in neutral or drive, read many ideas from low or high freon, iac, throttle body cleaning, o2 sensor? no codes thrown. Maybe coincidental but was discussing o2 upstream sensor recently on this board. The car experiences the same symptoms while driving.

I did a timing belt replacement on the car. Checked the marks carefully for alignment since it took me nearly 2 hours to get them right to begin with, started the engine and it ran fine. Now, after putting the car back together again, the car will crank, and as long as I give it gas, idle smoothly at RPM's over 1000. Once I get my foot off of the gas, it will die, and I mean at once, no sputter or anything. I have pulled the IAC valve and cleaned it, and it seemed to do a little better in that i can let my foot off the gas and it will idle around 1000 RPM and slightly below, but it will eventually do the same, and the idle is ruff. I have also noticed while maintaining the higher RPM, there appears to be a slight surge in the RPM as if the car is trying to idle itself even higher off an on.

The revs surge from low idle to high (about 1000 rpm) every few seconds, but only when the truck is in gear,and the AC is on. What it could be. Also is it something I could fix myself? I have been driving with out the AC for a while but going into summer I need it on.

My 2003 6.0 has started to surge at idle after driving for awhile. Like when I drive to work (30 min) and pull off the interstate the idle will bounce around at the stop sign (only jumping like ~100rpm). Does this sound like the ICP to you? I've replaced it once before and am wondering if it's time to do it again?
Also the truck will sometime be hard to start. And when I say hard to start I mean turn the key, let the GP cycle the turn to start and it just cranks. But as soon as I turn the key back off and cycle the plugs again it'll fire right up. It doesn't seem to matter if it's hot or cold. It's been doing it since I got the truck. It seemed to get better after the 1st ICP but didn't completely get fixed.

I have a 1991 Mitsubishi Mighty Max 3.0, and it is giving me some trouble. If the MAF sensor is plugged in the RPM's surge up and down, anywhere from 600-2000. If you unplug the MAF sensor it runs smoothly around 1600 RPM. I put in a brand new MAF sensor and that didn't change anything at all. Everybody I talk to says it must have a vacuum leak?

I have a 2000 Jetta 1.8t. I am having a sudden boost surge problem. It seems no matter what gear I am in if I get on the gas when getting on the highway or whatever to just get up to speed in a reasonable amount of time, the boost just increases like crazy. I do have Gonzo Tune and know I should have a faster response but I have been in higher built mk4's and they don't do this.
I have done the following to try and fix problem and some cause it was just time to replace:
New MAF
New N75
Fixed Leaks
New Plugs
New coil packs
New Fuel Filter
I do have a boost gauge and when cruising my vac is steady. The sudden surge of boost goes to almost 20 psi. I have thought of replacing my wastegate actuator since I have heard that can be a problem?

So I had this issue with my idling at 1300 rpms but every now and then it would idle at 400 and barley run then one day it didnt want to idle at all so I checked the iac and it was bad so I changed my oil, fuel filter, iac, cleaned my throttle body, fixed a vacuum hose, and cleaned my air filter.
When I started it it idle at 2200 I drove it a little and it dropped down to 1300 the next day I started it and it idled at 800 and staid there for four days now it idles at 2000 then will drop down and surge between 1300 and 1800.
I read that the oil you apply to the filter can contaminate the Maf and you should clean it but a lot of people said the one on a vr4 can't be cleaned while others say it fine. Is there a way to check the maf?
