Now it is beginning to cut out while driving. I had gone approximately .5 miles past the stop light and, while driving in a straight line at about 2,000 rpm, the engine quit. It immediately restarted and I completed the drive to the office when another symptom began. When I pulled into the garage to park the car the engine began to oscillate between 1,000 and 500 rpm and run very rough until it just stopped. Again, no codes are showing on the DIC or on my OBDII scanner.
I will be "head down" in the engine bay this afternoon trying to see if I have a loose ground or if a spark plug boot is not firmly seated.
Anyone have any ideas of what could be causing this? I'm at my (half)wits end.
