1995 Chevy Caprice V8 Two Wheel Drive Automatic 122000 miles
I have replaced plugs, opti spark, mass air flow, computor, and o2 sensors but still have a back fire comming from the intake air filter. This hapens at a high rmp. Also idels rough and has no power like a lt1 should. The drivers side old plugs were black but passengers side were good. I do see some improvement since the opti and plugs were changed but still that darn back fire from the air filter.
