Turned out that my ecu was bad replaced it and idles 100% better now. The only question i have is what would cause alot of popping out of the exhaust when i down shift. its a stock 302 with stock cam and gt40 heads with cobra intake. also has 24lb injectors, bbk massair and bbk throttlebody with bbk longtubes and h pipe with single chamber flows and mac chrome tips. I know for shure its not detonation. What could cause this? Thanks!
