Hey everyone- im new to this dsm world i have 99 gsx automatic and everything is stock except for i have a bomz racing cone filter and a aftermarket catalytic converter and a magnaflow muffler. Well first my car backfires a lot when i accelerate at about the 4000's and i dont know why . second my check engine lights came on from that I THINK. and thirdly my car is really really slow off the line is that normal or could something be wrong ?
