So I posted this in the performance section with no response so ill try here. I got a 90 sc with around 118k PLugs are newish and motorcraft DP and the wires are accel cut to fit. The issue is when Im at a stop for more than 5mins the idle will go to crap start jumping from 600 to 400 to 1k and all around and check engine light pops on once I move the car and get on the gas everything goes away, what could this be?? No vac leaks from what I know. end sometimes not all at a red light the idle will be fine other I will get a miss.
