Turned off o2 feed back control and i think it has helped abit, but still fumes, vapour coming out the exhuast and a very rough idle.
I will get another o2 sensor tomorrow (will try for genuine but will get el falcon if cant go geniune). If I install this and it fixes the problem, should I try and plug the air/fuel ratio back in?
Other mods to my car is, exhaust, pod filter, blitz bov, tein ha suspension and I have a gfb atomic boost controller.
Thanks.
