Symptoms include:
- Wandering idle ( 800 at one stop light, 1000 at the next)
- Bad mpg (lol?)
- Poor throttle response
- Lack of drop in idle when TE1 and E1 connectors are jumped
Unplug the TPS and if it runs better, you got some work to do.

I had all the symptoms listed about when my TPS took a crap...
Like Jay said, I unplugged mine and left it unplugged for 3 days till I got a new one cause it ran so much better.
So try that first and see what happens.
Good luck

Ya I don't think my TPS is as bad as that yet...when I unplug my TPS the car runs worse and I don't accelerate well at all either.

haha.
Glad someone posted this. I think mine is crapola also. Tried to adjust it via 4crawlers site but my volt meter won't give a steady reading so I think it's gone.
Mine is hard to start, will turn the key upwards of 5 times and then when it does decide to run it will shudder for about 10-15 seconds then jump up to 1500 RPM. Once it warms up it will settle at 1000, and when it has been running I sit at stop lights and it drops to 7 or 800. Now that I know you can disconnect it, I'll try that tomorrow

I also found it a LOT easier (3VZE) to take off the throttle body and use my ohmeter to measure what needed to be measured. I was able to re-use my throttle body gasket as well.

BoostinChick...
This is debatable, but I believe you may be seeing the results you are by unplugging the TPS is because it's on the same circuit as the auto tranny. I'm forgetting at the moment exactly how this is, but it has some management over the tranny and consequent engine load. Sorry for the vaguery. I suppose I should get more details, but I'm feeling too lazy at the moment.

My TPS worked just fine .. along with other units I tested .. my problem turned out to be the throttle body . throttle body shaft bushings to be exact ..
seems with th 260K I have on my unit , like a carb , the shaft bushing have warn , and now creating a vac issue .

Wow....that's a new on me. Never heard of that happening. Something to keep in mind, I guess.
So, how'd you figure out it was the shaft bushings? What clues were there?

No, it's not me....although, rather similar in features. I'm much thinner, though. And, were that me, I wouldn't be wearing underwear.(Too much info?
)About the avatar and where it came from........that's courtesy of a4runnerfreak....aka Tony the Mobster. I thought it was funny and too much like my silly side. So, there it is. Viewable for all. I've been pondering a change, though.
