7mgte stumble HELP

[ccguy]

thanks for the reply. yes i have tired another ecu. i have a spare. the tps has been rewired with new wire so i dont think it is that unfortunately.
but yea it seems like the afm is telling the ecu it is taking more air than it actually is.
or the tps is telling the ecu that it is floored. this would explain why the motor acts like it is being floored under load ( with the throttle body barely cracked and the motor continuing to rise in rpm like i am flooring it.
also while having the throttle barely cracked and rpm like 3000 the vacuum will be at like 0 but i can hear the waste gate open and the woooosh from that. but it is not boosting.
i really wish i had someone within a 4 hr drive that knew stuff about this motor or had a supra to help diagnose the problem.
but i will look back and check out what you suggested. thanks
