i just bought a 96 camaro con'vt with the 3.8 . it has a cold air intake and headers. it has been backfiring throught the exaust. could this be due to the cold air intake since i live in minnesota and it is winter? this is what i have been told. i'm leaning towards egr valve or injectors. thanks for any advice you can offer

I had the exact same problem. My #6 plug wire was melted completely.. I would look into MSD 8.5 wires and some spark plugs if I were you. Our cars are notorious for bad plugs and wires.Originally posted by thcredneck View Post

This would give some insight as to why it's missing. Instead of blindly spending money.Originally posted by bigbrian442 View PostsigpicComment
