ok, i took my 93 se to a mechanic to check the steering and when i go it back,i almost cried. he let it sit for more than 2 weeks without being started in the snow cold winter of michigan. when i first start the car, the idle is fine, but when i put it into gear, it idles high and without even touching the gas pedal to speeding exceeding 40 mph. then when i put it back in gear it idles at 3000 rpm!!!!! im so worried about my baby, the ses light has come on recently too, and it shuts off occasionally. the mechanic is closed for the weekend now and i need to use my car a lot this weekend........HELP!!!!

Reset the ECU. Pull the battery for 30+ minutes, and you should be okay.

its still not workin......now it shifts really funny, just not the way it should. and when i started it up after having the battery unhooked, it seemed the same then i put it reverse and it just started pulsating, it did that til i got out of the driveway and i punched it then it just didnt respond and felt it just in too high of a gear and wouldnt down shift to accelerate and its just real inconsistant now.

I think there maybe a vacuum leak somewhere.. check the vacuum lines..

You have an SES light? Have you pulled codes yet? That comes first, even before asking a question. That code will be the key to the fix.

i dont have a reader so i went to the autozone 9 miles away and i got a code 21 saying that the throttle position sensor or wiring may be faulty, so i bought a new TPS but i cant take off the old one cuz the screws are on the bottom of it with little room between it and the exhaust manifold making it difficult

from what i can tell i have to take the entire throttle body off to get to the TPS on the underside of it. i cant reach any tools back there.

You don't need to have your codes read. 93 was the last year of the flash feature. You can read your own codes with nothing but a paperclip. The procedure is in Techinfo.

You can change the TPS without removing the TB. In your case, I'd buy an offset screwdriver. Removing the TB isn't so bad, though, and you could take the opportunity to clean it. It'll help performance alot.

To remove the TB:

1. Remove the plenum hose to the airbox.
2. Remove the MAF sensor (black square with wiring harness) from the TB and put in a safe place.
3. Disconnect the IAC valve and TPS.
4. Remove crossover pipe heatshield in order to remove throttle cable bracket.
5. Remove metal clips for both cables, and put in a safe place. Remember which cable was top and which was bottom.
6. Remove the throttle bracket.
7. Remove three nuts/studs and remove TB. Pull IAC and clean it with intake-safe cleaner and a toothbrush. Do the same with the TB, paying particularly close attention to the IAC passage.

Install the new TPS before putting it back together. This should take about 3 hours for a first-timer, and the only part you need to buy is a TB gasket. Torque specs are in Techinfo.

thanks ill have to give it a shot tomorrow in the light
