ok guys so here are the symptoms:
car revs freely to redline when in neutral
car revs freely to redline with %0-%75 throttle
car revs terribly from 2900-4200ish rpms at >75% throttle.
so basically under heavy load, hesitation at mid-range rpms.
i did as much research as a i could and found some information, but nothing that perfectly fits my situation. i can start replacing everything under the sun, but am looking for suggestions on what to check/replace first.
AIR:
already checked for vacuum leaks, nothing seems to be amiss. checked afm for free movement, checked out fine. going to also try one that is a known working one.
SPARK:
can this possibly be something with spark? cap and rotor aren't very new. wires are relatively new in their lifetime. going to try a different known working ECU, but the ECU is not that old (was replaced once already)
FUEL:
i really can test the flow of the injectors with the tools i own. could a dying pump cause this? or perhaps a clogged fuel filter?
any input is greatly appreciated.
