How to adjust idle?
hot engine ?, cold or both,, EFI runs in 3 modes, cold ,warm and hot.
which engine option (displacement)??????
there is no idle adjust, that is the PCMs, job 100%, all the time.
Carbs are gone.
here is rule one for all EFI.
idle is the last thing to work correctly.
anything the causes a gross imbalance of engine power to engine load, under idle will cause , idle controls to fail.
low idling causes. (over 50 but, here ar basics)
1: AFR (air fuel mixture too lean) usually surges. (clogged or leaking injectors. or fuel pressure way to high)
2: air leaks, cause racing, so not that. (speed density car ,if is)
3: egr stuck open. low idle and misfire.
4: ISC stuck closed (IAC electric)
5: cam belt slipped, timing retarded, compression at 1/2 spec, and well, valve will bend soon....
6: CEL glowing running? can be in limphome, limp cancels Idle controls (in may cases) RTM read the FSM on DTCs.
if fails hot?, is hot = 180F temp or more? "thermometer time"
if not, the PCM goes , quite nuts.
