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.
