Lately,when I don't use the Bullitt for a week or so,when I go to start it,it won't idle at all. It will cut off right after it fires. So,I give the IAC,a couple of taps,try starting the engine and after 3 more times,it will idle as normal.
Is it the IAC motor just being sticky,can it be cleaned,or is the motor just getting tired,needing replacement?
These things aren't cheap,best dealer price being $120.00! NAPA was $130.
Funny,how my old 1995 F-250 keeps on running fine,after 90,000 miles,with it's original everything!
0503 only has 17,000 miles.

Pull that baby off and clean it with carb cleaner of brake cleaner. Be generous with the cleaner, may help.

Cars love to be used. It is when they don't get used things stick/seize as in your case, thats why i'd rather have a average mileage car than a low one.

As recommended, try cleaning it out first, its a much cheaper alternative.

They are not expensive at all (in my opinion). Cleaning the one on 2180 helped for about 2 weeks then it came back. I bought a new one no problems since that was about 13,000 miles ago or so.

I'm thinking now.... When the engine is off,is the IAC valve in the completely close position? So when you start the engine,it opens to a set value? When the throttle is opened,does the IAC close or stay at the same hot idle position?
What I'm thinking is would a fixed,manual type idle orifice work? Think about those idle restrictors that limit the air flow for a quicker responding idle.

My GT had the same problem last year. I tried cleaning it, but it only helped for a about a week. I ended up replacing the IAC altogether.

I'll second that! They are meant to be driven, especially with all the gizmos and gadgets on them that make them work right to begin with. Every low mileage used car I have ever bought has been a a PITA for the first year or so. The Bullitt has been no exception.:eek: :rolleyes:

My 1994 F-150 with the 300 cid six has not had any issues save a radius rod bushing in the front suspension wore out prematurelly, and the A/C compressor clutch failed at 150K miles. Then again, the six was a commercial application engine.:wink:

I drive my Mustangs,but they haven't been daily drivers. I do run them at the track,once in awhile. However I try to keep the miles low,since there are no other new factory hot rods,in my future. What I have is it! Can't afford no more new car payments,on my limited income.
