Q&A

I looked it up and it does have an idle air control valve.
Could it have something to do with timing. Cuz I had to pull out distributor just a but. But engine startts right up instantly.
Just the high idle and dies when put in gear. I can't hear a vacum leake that will make it idle so high. But won't a vac leak drop rpms?

I cleaned the IAC and the RpMs dropped to 700-900 and now it dies after a minute after it is turned on. And when I put it in gear.
It driving me nuts. What else can it be. I replaced the ect sensor and does tje same thing.
Could engine Vac is at 20in. And egr works. I apply vacuum and engine wants tO stall..
Spark plugs r new. What Can it be.

Try cleaning the idle valve. Remove it from the engine, and clean any carbon out of it that you can see. Try searching for this term "clean Ford idle valve" and you will find instructions on how to do this.

does it die when in gear perhaps drive or reverse?...if that is the case and you are positive everyhting else is good, i suspect torque converter locking up...
