Good morning guys. Will you please assist me with my 320i E90 of 2006. The misfires and I have replace Vanoses, vvt motor, oxygen sensor before cat, coils and there is no change. It would at times take too long to respond even when the accelerator is full depressed. I have spent so much money on this car and it is still not right. I am in Pretoria, South Africa. Please assist.
