here is my rich list , huge.... try for you.
1: in limphome mode ECU, CEL flash codes not 12 flashes.
2: fuel pressure out of spec, not is not per above.
3: injector leaking or hacked wires to it to gawd knows what.
4 :any of 2 injector 0-rings leaking on actual injector in TB.
5: O2 bad, or exhaust cracks near it cause it to go NUTS (sets o2 max lean 0volts and ECU goes MAX rich)
6: if the Distributor has no cmp like this 94 has, that means it has advancing weights inside that can freeze(rust) and MPG is horrible.
7: Map bad or hose to it clogged or cracked. map never fail only vacuum to it fails for all the reasons, even the nipple source vaccum clogged or susuki silly filters on this hose clogged up.
8: spark timed wrong, or spark bad , coil bad, wires HV bad , spark plugs bad. cap rotor bad.
9: vacuum leaks are no it, well except to MR, MAP.
10: cam belt slipped. or was timed wrong last service 60k point.
11: CAT melted, if car has full power this is not it.
anything else would be super obvious air filter packed in crap or critter nets from end to end, air intake.
12 :compression very low. 150 par wide open throttle.
13: ECT bad, reads 10,000 ohms hot engine, not 300 and will burn a tone of fuel ever time. I call this stuck in ALASKA mode.
that is all I can think of top of head. late.
this may match ours, its 1994 sammi
unflood mode is cranking only cuts fuel, if ecu sees spark end it cuts fuel running.
