WTF is it

[FEARED]

Ok. ANOTHER problem. My ride is currently having a problem idling at the right rpm. Allow me to explain. If I even attempt to drive the car without at least a 10 min warmup the idle will drop to 500-300 rpm during a normal stop and during a quick stop it stalls. When the car is fully stopped the rpms will climb back up to around 700rpm. Once the car is warm its pretty steady at 700rpm which is still about 200-300 rpms lower than my previous 2001 GT. I know this isnt normal, but I'm not sure of the cause. My initial thought was vacuum or possibly a brake booster as it only occurs during braking. However, my old 5.0 had a brake booster that was leaking so badly it sounded like an unhappy snake was trapped under the dash and it never had any problem idling or dropping rpms during a stop. So, WTF is it?

All I know is this is ! My ride has only 34k on it and the damn thing is a hazard on the rode. If I'm in a panic stop and the car dies I'm screwed! I'm not to interested in replacing the IAC because I know other folks have had no luck with that replacement. If anyone has ANYTHING on this PLEASE lend me a hand.

go to the dealer and tell them you need in IAC for your stang. it shoudl cost you between $40 and $70 depending on how much they sell it to you for. 2 bolts and some carb spray to clean out the passages.

I understand what you are saying. I suppose I will remove it and clean it out, but as I stated before I've seen a number of posts from other members that have replaced the IAC with no resolution. I'll post here again after I tackle the cleaning over the weekend or sometime this week. If the problem persists I'll go ahead and replace it and let you guys know wtf happens. BTW, you guys with normal idles are typically around 900 are you not?

Thanks,

mine idles at 750.

I recall my 01GT idling around 900 and by looking at Spreadman's 4.10 vidz it looks like he's running around 900 as well. 750 seems a bit low to me.

I guess if mine would STAY in that range i'd be happy with that but 300 is not cool.
