i have been working on it some more with a couple of toyota friends. we went back over everything i have checked. and found everything we checked to be in spec with the tsrm.
we hooked up a snap-on scan computer as well. it threw the code 32 (HAC) since i had it unplugged so i could drive it to town. the tool said that with the hac unplugged the ecu will shorten injector duration. so why would it run better with the shorter duration like when i have the hac unplugged? what trims how long the injectors open for? could it be like i previously thought, with a rich condition and flooding the cyl with too much fuel to burn with the amount of air?
i went over the tps again and i get all good signals from that at the ecu. the volts slowly increase when i open the throttle. the idl opens at slight throttle.
i would like to have another harness to try? might be a bad wire in the harness that test ok but wont transfer the continuity when it counts etc...????
