2.8L 89 RS. dude my car is hesitating. when i speed up, the car hesitates. when i take my foot off the pedal, the rpm gose up and down. it even acts like it wants to cut off but does not. what is this? the IAC is new on the car.
Sounds like a vac leak at the intake gaskets...a very common problem for the 60* V-6's. My 3.4 DOHC in my daily driver was doing the same thing...the plastic intake gaskets was cracked in 3 different places.
