Motor is S13 SR20
problem is at idle i pull 10mmhg for vaccum and it idles really rough, and when the motor is cold its worse. The car seems to idle pretty rich too. Weird part is that if i dissconnect the MAF while its idleing the car idles alot better with no MAF plugged in, as soon as i plug it back in it goes back to crappy. What else might there be to check for a bad idle. Things i have checked already:
I have swapped out with a good Z32 MAF
Checked MAF wiring
Compression test equaled 153 psi on all 4 cyl
Checked for leaks in intercooler piping
Checked spark plugs
Checked for leaky injectors
Anymore ideas?
