Hey everyone, I was wondeirng if anyone has replaced their Idle Air Control Valve or ur TPS. I have a rough stumbling idle, almost like a missfire, but I do NOT have a CEL. It only does it under low throttle and idle at a stop. I reset the battery, changed plugs and all. I think my IACV has been slowly dying, but not to sure. LEt me know if anyone has replaced the IACV or ur TPS. It just started happening after a 4 hour trip through the mountains for some reason. Just lemme knowf ya replaced it and why.

I have the same thing but it started only when I got some water in the engine (misting of water from having a very wet air filter). I figure the IACV or the TPS got boned. I was also thinking I possibly got the MAF a bit angry at being wet.

I've replaced both..... but it was more of a "they didn't like having 19 pounds of boost" being blown through them kinda thing [:D]

I know on the non-SVT Zetec the IACV is on the Back on the Intake Manifold. 2 8mm bolts hold it in place. It's easier to get to from the bottom than the top. If you need one i recommend Steve at SVT Salvage.com If i would have bought my IACV from him, i would have saved $20. Even more if i would have forgot that my Step-dad works at Ford. It was a $120 part i got for $80 with the discount and it would have been $60 if i would have got it from him.

Call Steve at Tousley Ford
offering all OEM Ford parts at 10% over cost.

Quick question lil disco, why did u replace urs? lol Orange 19lbs im sure didnt agree with them, but what were ur symptoms of those 2 things being bad? idle? It drives great, just at idle, and VERy low throttle.

Well I had water in my TPS and it would start... once in awhile.

A bad IACV will cause a very erradic idle... always up and down.. sometimes it will hang, sometimes it will almost die.

I got K&N oil and water in my TPS once. ONCE!!! I was underboost and hit a very large water pudle!!! Damn them!!! It was cheap, like $30 bucks and two screws to replace. Fixed my stumble.

I've been having a weird irractic idle for awhile now. Almost since i bought my car. Took it to Ford and they say that it's supposed to Idle and the Rev's hang while shifting. Did my 2000 Intake Manifold Install and it hung Very Badly! Here's a couple Vids, you'll need Quick Time:

Yours almost seems like a TPS but at Idle it seems to Idle Right, but Steve at Tousley Ford can get you a TPS and IACV for a lot lower price than at Autozone, Napa and obviously a dealer. This Comming Paycheck, i'm getting a lot of stuff from him [:D]
