ENG: Cleaning out IAC Valve

[jay82985]

doing mine as i write taking a quick smoke brake ill let ya know if it help with my idle problem

[Mjfan12]

Did this and the fitv, and car runs much better. smooth idle, used to fluctuate a couple hundred up and down on a cold start, now seems to be stable.

the hoses were impossible to take off, space is too tight and I didnt have needle nose pliers, just bulkier slip joints.

so I left them on, and unbolted it, and I had about 3 inched of space in between the unit and the intake manifold. I just sprayed it with the cleaner, and used a napkin to clear the dirt away, cleaned it to a shiny silver.

Nice, I would suggest alot people try this first with any idle problems!!. I did mine this morning and my car runs like a pro. Took me a little over 30 minutes to do this but its worth it. Also, since my car was old, I would have to twist off stubborn hoses once I got the clamps off....Now if only I could get that antifreeze leak fixed...

I know brake cleaner works great on engine stuff, but will it damage that rubber seal ya think?

use a q-tip and try to avoid the seal

I did this back in oct of 06' and now again recently and It amazing what a difference cleaning it out makes. I used to have a stumbling right upon startup but after cleaning this w/ carb cleaner and using a bottle of Fuel injector cleaner, it took care of it after a tank's worth of fuel.

I just did it just now. Took me about 1hr. My was DIRTY!!!!!!!!!!! I have to keep spraying it and let it soak. I used Seaform Deep Creep by the way.

It was pretty simple. Now when i start the car it start alot smoother and run alot smoother.


Thank!!!

I think i may tackle this and the EGR tomorrow.

Take off the IAC valve cable

Do you mean the electrical connector

Also Im guessing that Carb Cleaner WILL NOT damage the seal, correct? So it can just be sprayed, yeah?

Also, is it a good idea to (or can you) remove the little screen on the right hole? What about the seal? Can/should that be removed and cleaned as well?

Anybody have trouble getting that bottom bolt??

My ratchet head was too fat and i couldnt fit the 12mm AND the ratchet down in there. And no, vice grips didnt work for me.

I managed to find a 1/2 socket that was shorter than my 12mm, but just my luck it required a smaller peg thing.

Its getting dark now, so..I'll pick up some PB blaster and try at it tomorrow.

heres mine...made a lil diff. but not like other people say...and right when i turned my car on it idled a lil high around 1100 but then it started to go down to around 900..
but it still gave me sumthin to do and now i know its clean

[MikeW]

Taking a quick break, but was anyone able to take out the little filter or no?

Mine was kinda of a bitch to get off, and btw i lost a shit ton of coolant. Maybe 1/3 quart...

I suggest having several rags handy.

[ancona46]

hmm i only lost a couple drops of coolant
