Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

knock & P0172



When my car started surging the scangauge was showing knock and HP so I didnt see if I got any missfires. Fuse 21?
 


Well as of the new IAC sensor heres what I got(all at idle):

IAC 2026
RPM 789-800
CMD A/F 14.70
MAP PSI -21.2
IAT 159
MAP kPa 26
Coolant 188
Boost -21.2
MAF freq 2947
Throttle V .49
Ignition adv 22.0
Short Tr -14.8
Long Tr -22.6
02 S1B2 985
02 S1B1 985
 
Adjusted (lowered) the FPR to 40psi @ idle. It's been a week now & no more gasoline smell or code P0172. Problem solved.
