I HAVE A 1999 BUICK REGAL LS, THAT RUNS FINE FOR 30 MINUTES AND THEN IT STOPS RUNNING. I HAVE TAKEN IT TO A MECHANIC WHERE HE RAN A DIAGNOSTIC CHECK ON IT. THE COMPUTER KEPT SAYING THE SAME CODE OF 1361 AND 1362. I HAVE ALRADEY REPLACED IGNITION MODULE, SPARK PLUGS AND LINE. THE MECHANIC CHECKED ALL THE ELECTRICAL WIRING HARNESS AND IT TESTED FINE. HE ALSO, TESTED THE POWER TRAIN CONTROL MODULE, AND IT TESTED FINE.

Codes indicate a low voltage atICM bypass if ICM replaced and wiring between ICM and PCM checks then replacement of PCM is next step. How did they test PCM I know no way of doing that and would like to know.
