last night coming home from south florida, went though some rain and my camaro started acting up. first it acted like it ran out of gas and just died, i pulled off the road and it fired right back up. as i was driving i noticed the tach would be arractticly jumping RPMs, and it would start to miss and die, but it still would fire right back up. it seem to run ok in 5 gear and at 3000rpms. i made it home. but now the car wont start. check for spark at plugs with no avail. check fire from coil and nothing. i would hate to go buy a coil and it still not work. how do i test the coil to see if it is bad. could it be the pcm, distributor, or what. please help.

 

Welcome to the board.

I wish I had a good answer. It would be helpful to know the year of the car...

On the LT1s the opti is fairly low (think waterpump/cam) so if you have an LT1 I would look there first (unfortunately). If it is the coil they are not that expensive and very easy to swap out. Try some various searches through the tech areas and I bet you can narrow down the list of suspects.

Sounds like the opti.
