i need your help again. i fixed the tps wiring and the tps is working perfect (as you will see in the video it shows how much throttle is open in volts).
itis a bone stock 1987 7mgte motor.
there is a hesitation, stumble, hiccup at around 2500 rpm.
it is running very rich and getting horriable milage.
if it is a cold motor it runs good for about 40 seconds then this stumble starts.
i have an inline walbro and a intank OE supra pump.
while driving it can rev above the biccup but if the throttle is barely cracked it accels like i am flooring it. when the speed catches up to how much the throttle is open it acts like there is a dead spot. and the throttle is like a switch between on or off.
if i rev it up and hold it at like 4k and let it off it revs down and almost dies or dies.
most i have boosted on that crap gauge is 4psi.
io have great vacuum.
