My van was having stallling problems at low idle. It would always start back up with a little time. This would start after a 10-15 minute warm up on the highway, i would get the off highway and the stalling would begin. last time this happened the car would not restart. I replaced the IAC but this did not help. I replaced Distributor cap and ignigtion coil 50-60$. Running Great. A big THANK YOU to this site.

 

Was your problem the coil or was it the cap?
