Luv my CRV

I have a 2003 CRV (which I have always loved) this is the 5th Honda we've owned and have never had these kind of problems!
Happens ONLY in hot weather, engine doesn't run hot - but tach starts to up over 2 on highway and doesn't drop down below 1 when in idle. If you get stuck in bumper-to-bumper traffic the engine is revving all over the place and you have to practically STAND on the brake so the thing doesn't take off on you!
Took it into the dealer and was told that they "think" it is the idle air control valve - that will cost $445 pls tx to fix and they "think" there is an "80% chance that will fix the problem". If it doesn't however, they "think" the computer should be changed out - to the tune of between $600-$900 - NOT including labor!
Called American Honda for help and was told that they couldn't help me because I don't have "a specific problem".
HELP! Anyone ever experience this problem? I truely cannot afford to fix BOTH of the things the dealership "thinks" is wrong and am at a loss as to what direction to take right now.
Any suggestions greatly appreciated! Thanks!

Had the same problem with my 2004 Crv. Luckly I have a manual transmission, and can leave it in nuetral when the problem occured. I had the IAC values replaced yesterday. It seems to have fixed it but we will see. Total cost for repair at Burns Honda - Marlton, NJ -$496.26

Same problem here. I have a 2002 CRV and have had the year from hell with it, from the AC breaking twice to this. I noticed the engine revving and the rpms rising when the car was in park and it was almost impossible to keep my foot on the break at a red light. The check engine light went on the other day and I took it to AutoZone to get them to read the codes. They told me it was the Idle Air Control Valve and would cost 330 to replace it. Hopefully this fixes it because I cant afford for it not to.

Other possible faults noted in my manual are intermittent short or open connection of wiring to the IAC three pin connector. Pulling connector off, check pin 1 reads continuity to chassie ground, pin 2 has 12 volts(ignition on), pin 3 reads no continuity to ground, it goes to PCM.
Other items to check: PCV hose connected & not damaged; no vacuum leaks in air induction system.

i just replaced the idle control valve on my Honda CR-V 2003. at the tune of $549.5. My car was stopping at every stop light and the engine would just die down. the dealer diagnosed the problem to be the Idle Control valve. Otehrwise, this car has been good to me. have taken trips to Canada, New Mexico, Arizona, etc with no other problems.

I just replaced the idle control valve on my Honda CR-V 2003. The engine was 'surging' while idling and would lurch when driving very slowly in 1st gear unless clutch in. Symptoms were intermittent. First trip to the dealer cost about $100 to clear error codes but not this problem. I drove it until it presented on every start-up, then brought it in. Fixed now, for $633.35 CAD. I'm still very happy with this vehicle.

Not sure what you mean by "reset" the IAC? If it's defective, gotta replace it.

Not sure if this is the same problem I'm having - I took my 2000 CR-V to just my local mechanic, he diagnosed a problem, but told me it was something he was unable to fix - I thought he told me it was an air intake valve, but maybe it was this. What happens with me, is when it is idling with the a/c on, the rpm's drop way down and it's almost like the engine is about to die, and you can tell the a/c compressor is constantly kicking on and off. I haven't been able to get it fixed yet, just been having to drive it - don't seem to notice a problem when I'm just driving, a/c works too well, only when sitting still or in park. Thoughts?

The computer tells the engine to speed up the idle when the AC is on, to compensate for the added drag of the compressor. So, yes it could be the IAC valve. It's not cheap, so I would have the problem diagnosed before changing anything.

Well, I'm about to have to travel in this car as well - been driving it a while with this problem, but I'm about to have to take a pretty long trip - am I looking at any permanent damage or any possibility of getting stranded?

Unless it gets much worse, I think you'll be OK. It'll be annoying while stopped at a light, that's all. Shouldn't damage anything.

i got mycrv 03 icv replace the other days.it cost me 650 including the cleaning of the air intake valve.its a pain in my pocket to have that repair.

the syptom is just like what u got in your car.
it start and engine will die.engine rev dont reach 5000 rpm.i use to step on accelator more on the stop ligth so the engine keep reving,if ill let go on the gas pedal,the engine will stop.mine is ex model.
they suggest to clean the air control valve which cost 150.they said its the reason why the icv malfunction.

I believed its a sensor switch from your a/c to the ecu to the iacv which controls idle speed.

Dude, why paid 150, use a carb or brake cleaner, spray in the opening before throttle door then let it soak for awhile.
