I recently bought a '92 AWD turbo laser with a JDM engine and a turbo back exhaust.
My questions are:
1)What is most people's normal idle?
From what I can tell I'm idling to high at ~1600 RPMs.
2)Is the idle suppose to surge slightly?
My car idles very steady at 1600 RPMS until it gets warmed up, then it will drop 100 RPMs every few seconds. When this happens the A/F gauge says that it runs completely lean and the exhaust makes a kind of "airy", almost like it backfires, but not as bad.
The aftermarket boost gauge is sitting at -18ish the entire time it idles, even when it drops the 100 RPMs, but the dash gauge sits at -7psi and moves slightly down.
If this isn't normal do you think it could be corrected by adjusting the Base Idle Set Scre? I haven't seen any vacuum leaks, but could this also be a potential problem?
