My 92' talon will idle in the driveway forever, but when i take it out it will drive for 20min then the engine light will come on and the rev's will go from about 1800 down to 500 and back up and down and then stall out. 20min later the car will start up again no problem and will drive for another 20min? could it be a coil pack, crank position sensor??? any help. also where can i get a diagnostic on it because the chrysler dealer coudnt get into it, nor could my buddies machine???
