Default Broken Valve Spring??
Sorry to make antoher thread but I need some input. The car drives great while normal driving it, but under load it backfires like crazy. The tune is looks great air fuel looks great, plugs look great, no codes being thrown. My only other guess is eaither briken valve spring or coils. I just could not understand why it drives so great while normal driving if it is a broken valve spring.

Thought I had the same thing but found out it was my head gaskets and now it runs great. Do a compression check and see where its at.

If you have a broken spring it won't drive normal, you will have some power loss in that cylinder.

Look for the compression similiar between all cylinders...If you see a significant drop then you know that you have a blown head gasket... Have you pulled your dipstick to see if there's any water in the oil??
