it goes
maf -> computer -> injectors
so,
its either the maf, computer, or injectors (and related)
->things that f#$*& with maf:
wrong maf
bad maf
bad maf wiring
bad maf grounding
poor maf placement (too close to turbo, turbulent tube, no recirculated bypass)
leaky maf plumbing (boost leaks and air leaks)
improper use of maf (boost leaks, blow off valves, poorly designed tubes, non recirculation bypass)
!>computer issues related to rich a/f ratio:
bad ecu grounding(corrosion), bad (maf/tps)sensor grounding
poorly tuned, improperly tuned
wrong maf
(unrelated note to check timing)
☼¶injectors issues general store for rich a/f ratio:
leaking injector O-rings
too much fuel pressure (rare)
Injector too large for idle speed/minimum pw (2000cc injectors)
