I have a 1995 240sx, it backfires when you let go of the gas, usually at lower rpm's (2-3k) sometimes, but less frequently at higher rpms. I also noticed there is much more significant amount of backfire if OD is on. (its a auto)
I have a GP sports exhaust with 3 inch piping, running on a stock intake. I would like to know if the car is running rich? Or is it just because of the 3 inch piping due to the lack of back pressure. Should i worry about it?
