Well, I went to go to work about an hour ago and when I was pulling out of my driveway, the car is having a hard time staying on. It is only when I don't have my foot on the gas though. If I sit there with it in neutral and hold my foot on the gas keeping the RPMs at 1500 and above, it will be fine, but as soon as I let go of the gas, it goes down to below what the usual RPMs are at idle and bounces around until it stalls.

It will also stall when I am driving. I will be coasting along and if I don't have my foot on the gas, it will just cut off, so I have to bump it up into neutral and hold my foot on the gas to prevent it from stalling when I am moving. I went to the dealer and was talking to a tech and he said it sounded like the IACV. He told me to unplug the wire from the IACV and see what that did, but it didn't do anything.

They were trying to charge $168 for the part and 2 hours for labor. I am thinking about checking with one of these online dealers and ordering the part myself and replacing it when I put on my Outlaw Engineering Spacers when they come in in a few days as well as clean out the EGR port. I just want to make sure that it actually is the IACV that is messed up, so I don't spend all this money just to have it be something else.

I called my boss and told him that I couldn't drive tonight because of the way my car was acting. When I am driving and it stalls, I lose power steering and brakes so I would hate to be right in the middle of a turn or something when it happens and go straight into the ditch.

 

check with dnd- he had a new valve in the box on Black market- turned out his miss/vac leak was really the rear motor mount- turns out they are vac assisited! who beside fsttyms knew this!!!

 

Just take yours off and clean it. and add a bit of wd40 to lube it. Also clean your TB

 

I actually cleaned the TB a few weeks ago, but I will again when I get everything apart for the spacer install. The reason I was asking about a new IACV is b/c the tech told me that the IACV is "not a serviceable part". He was probably just saying that to get me to agree to the work and get the new one installed.

But, from the symptoms that I have listed, is it most likely the IACV that needs to be cleaned/replaced??

 

I went to Proctor Acura to question problems w/ my IACV and they said the only solution was to replace it. I told them that I'd wait it out because it was a rediculous price. About 20minutes after leaving the dealer and a little drive down I-10, the IACV was perfectly fine.

You're problem doesn't sound like my IACV problem tho so...???

 

Yea, I'm hoping it's the IACV and not the fuel pump or something. I will start looking at some online dealers and see how cheap I can get one for. I might just try and clean it when I have everything apart doing the spacer install, and if I continue to have the same problem after I put everything back together, just get a new one.

We have flag football practice tomorrow afternoon and someone on our team used to work where I used to take my car, A+ Dealer Alternative. I am going to have him look at it and hopefully he can give me some insight on this.

 

Just wanted to thank salvo for his post. I took his idea and just went on a drive. As soon as I started the car to go, it was doing the same thing; stalling as I wasn't moving. Pulled out of my neighborhood and at the first red light I was waiting at, it stalled before the light could turn green. I floored it on the way to the interstate, hitting vtec and redline in 1st and 2nd gear. Floored it a few more times on the onramp and on the interstate as well. I pulled off the interstate and was waiting at the first light and low and behold - no idiling problems.

I don't know if it was just a little piece of dirt in the IACV or dirty injectors or what, but the spirited drive fixed my problem, for now. Maybe all the air flowing through the intake broke free whatever was stuck, but it idles perfect now just like it used to Weird.

I was getting some bad gas mileage so I decided to baby the throttle this tank to see if that would help with my mileage. This is when the problem started, when I was about 1/4 way through the "babied" tank. Maybe my car was just telling me to stop treating it so good and that it loves to be abused.

 

And thats why in post #3 i said to clean it and spray a tad bit of lubricant into it. ( a acura tech informed me they do that first to see if it works and it usually does)

 

sold mine some time ago for 40 shipped.

 

Yea, dnd I did a search for your BM thread and saw that they were already sold. I just got my spacers in the mail so I will clean it out real good and if it continues to have problems, I will get a new one and replace the whole unit. Is this a wear part that usually gets replaced after some time? (Mine is a 99 with ~144K miles)

 

mine had over 200k on it and ran normally. They are prone to clogging/sticking though.

 

What was your rear mount issue. I changed my rear mount with a bunch of other parts and my rpms drop below 750 and stall when its coming down from an acceleration.

Any ideas? What did you experience with the rear mount.
