My ED rocks but it stalls in reverse and when the A/c is on
My car is stalling in reverse.
I just had the head gasket done by Ford and when I got tit back, it idles funny.
Its fine when cold cause the revs are up a bit, but when you hot start it, it idels just above the bottom of the lowest graduation on the tacho (600rpm) and when the a/c ticks on it shudders before picking the revs up a tad.
When i put it in reverse at the same time (when the car is hot started) it almost stalls then revs to about 1100rpm almost stalls then runs really slowly to the point where it drops off.
it doesn't do this in drive though.
Whats doing? Is it because the ECU is reset and it takes a while for it to re learn? or is the idle screw need a turn? or did ford **** my ED?
