Help guys! The other day my car started running really bad,black smoke, wouldn't hardly idle and the scanmaster was only showing------ on the screen. I found and repaired a vac. leak, reset the ecm at the orange wire and restarted the engine. This time it seemed to run a lot better but threw a code42 I didn't take it on a test run however, the code happened at idle. The next day I reset the ecm again and it didn't throw a code at idle so I took it for a run. It ranlike a scalded dod! No code what do you think?

42 should not have anything to do with the car running rich.
Sounds like an electrical fluke to me unless it comes back. I am surprised that fixing a vacuum leak cured the belching black smoke, also.
Maybe a time for an exorcism?
