To check your TPS voltage. Get a voltmeter with super sharp tips so you can puncture the tps wires to test. Turn the key on in your car but leave the engine off. Set your meter to DC volts and test the voltage between the green and black wire on your tps. It should read between .96 -.99. If its in that range, check that the voltage spike is a constant spike by turning the throttle to WOT. Once at WOT, you should read close to 4.5-5v. Also check the voltage between the orange and black wire, it should be close to 4.5-5v. I might have switched around the two wires because I'm going off of memory but either way the black is ground and you only have two other wires there so just test them both. If you find your TPS voltage is out of whack, post back here and we'll take it from there. Sorry if this is confusing but I can't explain it in an easier way. Also to check for codes, you have to count flashes, you know when you're doing it right because when the codes repeat themselves, you should have WRITTEN DOWN two sets of codes identical to each other. You have a 94 so I think you may have 3 digit codes. Just try it until you get it, it's not that hard. Long pause between flashes means it's spitting out a new code. Short pauses means it's just another digit. Theres a link to how to do this. Fogged306, where you at with the link. If not check out some of my threads, I think its called "New Member Needs Help Desperately" or "wiring harness". The links to testing a TPS and Codes are in one of those two threads.
