I need some help finding a site that will tell me how to change my coils. Apparantly my v6 is running as a v4 b/c one of my coils is dead. My car shakes and doesn't shift right and smells like gas. Shop said if i replaced the coil it would stop. How do you replace the coil.
1990 Chevy Lumina
3.1 V6
156,000

 

Not knowing much of anything about Lumina's I would guess it's a pretty easy job. Find the coil that's misfiring. Once you find the culprit it should be fairly obvious how it's mounted. Remove it and install a new one.
