Hi guys and girls,
I own a R32 gtst and I now find my car back fireing under hard load/under hard acceleration. I have recently replaced my water pump and timing belt (professionally), and have been told that this back fireing may be caused by the engine running lean, as the car was running perfectly fine before these replacements, and run's down eastern creek. i have asked many friends. including mechanic friends, and have been given answers from coil packs, timing, plugs and even fuel pump issues, and i am now a little confused. For those who have an idea, the car is totally standard, and i would appreiciate any answers to get an idea of the problem. P.s i have been looking at shops that have the software to tune my care at a reasonable price......any ideas people??? most want to cost the earth, or dont have the software and cant/wont even help at all.......
