New Guy Hello / 1992 Suzuki Sidekick Multiple Issues / What to Tackle First?

[fixkick]

ok your maf is ok, i had the wrong DTC ,
the 1992 car, is the only 16v made with NO IAC
its not there.
so if the PCM tells you its missing that means some bad guy put in the wrong PCM.
93, to 95.
wrong.
that was easy ,see this many a time.
here is the list
is this uSA car?
USA 1992 Suzuki Sidekick JX 16 valve, Federal, Automatic, 4WD , yes.
federal is USA fed. hood sticker says complies with fed laws. bla bla.
FED.

here they all are. varies by 4wd /2wd 2doors and 4doors.

E3 = fed, E33 = calif. on chart.

58B40 is fed ecu , no iAT
58B30 is calif with IAT
or someone put a 94/95 ECU in your car. all have IAT.
the side of ecu has these letters sticker above, and letters "US" for usa spec ECU.

the 16v engine really does not need a IAT its only for super fine tuning smog. i bet your IAT connector is missing too, as it should be.
the MAF is temperature compensated, is way.

the real problem on your car is 2nd gear. trans in limphome.
TPS is top billing failure, i bet it can be calibrated and is ok. just betting.
