 hey guys i hope you guys have an idea im stuck!!!!!!!
1996
toyota
corolla dx
1.8L auto
137602
ok i changed out the timing belt.it was just preventative maintanace. old belt was ok.. disconnected the battery for the alternator. finished and the car started up but idling really low and with slight misfires...if you give it gas slowly the engine smooths out but as soon as it hits around 2000 rpm it shuts off or if you smash on the gas shuts off or if you try to start it at half throttle it wont start..
i have checked fuel pressure, its at 40 psi...i checked spark its good and it keeps sparking even though it shuts off...no dtc's... checked map sensor and tps both have good ground and a good 5 volt refrence...i also checked for the ecu grounds cleaned them...i also check for batt at the ecu and ig switch power both ok...and i have cheked for ground also at the ecu and they r ok...if i add ether it will rev up fine...when i checked for injector pulse with it shuts off as the engine shuts off, power ok
have u guys heard of good psi but not enough flow?
man im stuck, stoped cas i dont know what to do any more sorry for the spelling im tired

mig; Sorry to say, but it sounds like you have the belt installed a tooth or two off. Bring it up on TDC and recheck your marks.
