Some of you know that I blew my engine in my 1999 P11. Not completely blown but blown piston rings. Anyways, I bought Luke's (G22DET) old motor from his 1999 G20 and swapped motors....I got it back running but the idle seems alittle rough and you can feel it when you put your leg against the door at idle. My friend sat on front passenger side and he heres a vibration noise in the headrest...Thats how bad it is....don't get me wrong...its not like crazy shaking but noticeable and hella annoying....I tried messing with the idle and did what the instructions on SE-R.net said...I fixed that but still the same old vibration...could it be EGR??? could it be the ground for the MAF?? HELP!!!!
