Throttle Position Sensor?

Alright so, 91 2.1 ALB, automatic, 99,000 miles.
Replaced my fuel pump like 2 months ago, then a few days later I have a misfire. As well as a very jumpy idle, between 5 and 15. Read my codes and got oxygen 1 and 2, map, tps, and tdc. Pulled my tps off and instead of falling on it's face it idled out fine, no miss. So instead of getting a new/used throttle body we ordered a tps from England and as you know the wiring is reversed. So my mechanic gets in and reverses everything and sodders it, and the idle is better than what it's been. Staying around 1000. Get in to test drive and it's a LITTLE boggy, put it in sport and tried to take off, bogged a bit more until about 3000 rpm and it TOOK OFF. Halfway down the road it started bogging a lot and actually tried to cut out. Pull onto a main road and it is almost unresponsive. Let off the throttle, pushed back on it lightly and it almost accelerated. Took about 10 seconds of repeating that until it would go anywhere, then it almost died again. Sounds worse than it ever has. Cleared my codes and none of them came back. Check engine light didnt even come back on. But the misfire and idle are worse than ever. Help???

Re: Throttle Position Sensor?

Junpy idle is bad fast idle valve!

Temp fix; remove one screw and loosen the other. take a wide flat blade screw driver or like item and carefully screw down the white plastic thing inside after you swing the cover aside. Don't force it. Snug is good. May or may not work. If not, get another one.

Rough running;
Do the basics.
