At idle my car runs lean at around 17 afr and while just driving around it runs between 14.7 and 16.0 afr. Under boost it runs in the mid 13's. It also has an inconsistant idle that falls somewhere between 600 and 1000 rpm.
I don't know if this is related to the problem above but after i clutch in to shift the afrs bounce rich (10-11), to off the charts lean, to the aforementioned idle at 17ish.
At first i thought it would be a vacuum leak but i checked the accordian hose, all intercooler couplers, and vacuum lines. They were all in perfect condition except I did have to reconnect one vacuum line but it was a loose fit to its nipple so i zip tied it down along with a few other slightly loose fiting hoses. However, the problem remained unchanged.
my current mods include:
large intercooler w/ 2.5" piping
wastegate shimmed to 9 Ibs.
Apexi SAFC
AEM UEGO wideband
ARP head studs
Autometer boost gauge
Thanks in advance for your help.
