my b16 runs great up to 99.9% throttle and then right when the pedal hits the floor at 100% throttle the engine bogs out and i have to left off the gas. if anyone has exprienced this, please help me.

 

tps or map sensor gone bad, maybe? are you throwing any codes?

Plugged cat?

 

Tp and Map sensor are both good i did a voltage test on them.
Also my VAFC reads 100% throttle at idle and vice versa for when throttle open counting down. I check and double checked wiring and its all correct nothing backwards. i even disconnected the VAFC and still had the problem with WOT bogging.
Im only throwing a code 41 (heat o2 sensor isn't hooked up thats why), code 20 for electronic load detector which the 90-93 tegs don't have, and the only important one is the code 14 for the IAC ( i need a new one, already tried cleaning out), but i didn't think that had anything to do with WOT.

Any guess's to what could be wrong??

i have a test pipe in, with a custom exhaust all the way back with no resonators. So i don't think it would be a clog.

 

I think it's the IACV. When I had my S13, the same thing happened.

 

Running a chipped ecu? If so try putting in a stock one and see what happens. If it is stock, can't help ya.
