can anyone help me out, i just replaced my coilpacks and changed plugs gapped to 0.8mm tonite coz my car was misfiring badly, took it for a test drive, it was all fine until i put the pedal down, hit boost and my car just farts, sounds like a bassy farting machine gun, but it also doesnt feel like its misfiring, its a whole different problem, i have no idea wtf is going on now, searched through some threads but i cant find the answer i need?
any ideas would be appreciated
