Car has wicked high idle right now... throws 21+22.. I extended the TPS and IAC wires maybe they came undone somehow and are shorting out? Car idles real high and when i jiggle the wires the idle starts bouncing around. Were talkin around 3000 rpms. I havnt really driven the car much since i made it a 3.1/3400 hybrid but i remember it idling real nice when it first started so i know something happend, maybe they just heated up and took a crap from being near the crossover pipe and turbo. Whats the best way to check the wires with a multimeter? Anyway the sensor itself couldve shorted out? thanks

with key on engine off, probe the tps at the connector. stick a paper clip (small) in each side (into that rubbery shit). i do that rather than jam the multimeter lead in there (cuz its fat). at closed throttle you should be reading .8 to 1 volt. (meter set to 20v scale). slowly open the throttle and watch the meter, the voltage should smoothly rise to almost 5 volts... you might only see 4.6 volts or something... but thats ok.
i really think you need to look at the wire splice point though... and solder them again... clean your IAC, confirm tps signals are good. -
ok im going to do that, thank you. I didnt have any time to touch it last weekend and i keep forgetting all my tools at work...I might just get new connectors and redo it the right way.Comment

Well in the middle of all this, i found my mystery oil leak, it was coming from from Pump shaft O-ring and dripping between the bellhousing appearing as a rear main leak...It was weird because looking down at it , you dont see any oil , untill i took the upper intake off, got my finger behind it and BEHOLD 5W30!!!
back on topic, I checked the TPS connector with multimeter and it seem to be getting ground and power. After a little more diagnosing, ill probably end up replacing the connector and the sensor. I hope this takes care of it. I appreciate the help from you guys.Comment

power and ground is great... but did you ohm? you could replace the TPS cheaply i suppose, but it would be good to test it first. chilton manuals have a lot of electrical specs for you to work with... libraries have those manuals you can access for freeComment

yea i was checking continuity of the wires from the splices to the connector pin, and then ohmed them to each other and to ground to try and find a short. I do some more testing tomorrow.Comment

Sounds like a bad TPS to me although it could be a voltage problem. GL.
