My1998 Dogde Caravan 58,000 miles. I noticed rough idle then engine stopped after a few miles. CODES were PO353-Ignition coil, PO505-IAC motor circuit, P1389- no ASD relay output . Repair shop replaced fuse and ignition coil from NAPA. I drove 180 miles and idle became very rough again. Replaced ignition coil. For a few miles there was a little rough idling then it became very rough and engine stopped. Replaced fuse and ignition coil again. After 10 miles it runs very rough again. The part of the ignition coils that overheat or cracked is the terminal post for cylinder 3 & 6. Is there something wrong with the spark plug or ignition wires for cylinders 3 & 6? Please help me. The spark plugs had been replaced by the dealer Aug.8 2006.

Already Tried:
First time I installed the coil there is a spark on all ignition coil post. When I tried to ground coil post for cylinder 1, no change in engine speed. This car has been check by the dodge dealer 30 days ago to fix wiring to injection pump #1. From that time until the rough idling occurred I have driven approx. 400 miles.
