Hey everyone my 88tc been idling crazy so figured tps needs replacement which is no big deal but did some checking around can't find one. Does anyone know where to find one I've checked Autozone,O'Reillys,Napa no one has one in stock or in warehouse. Can the sensor b interchangeable?

First you should run codes and see what is actually causing the problem.

It will show up when you pull the codes. If it's the tps that is. That'll show you whatever sensor is acting goofy.

AFAIK they are all about same, if it fits it works... I used one from my Bird on my '93 Lightning when it failed, fit and worked perfectly...

Hey OP, had the same problem with my 88 tc. Guess what??? A tps probably won't fix it.... Throw one on it tho. The parts stores love people who troubleshoot by changing parts willy nilly.

Seems like you're saying the car is trying to hunt for an idle

The idle speed controller may actually be carbon'd up on the inside

Use a cheap buttstuffog meter and unplug your TPS

Manually increase and decrease your throttle body linkage and watch the needle on the meter move

You measure from the black and the green and open your throttle slowly to maximum a couple of times

Next you test from your green wire to your orange and open your throttle and watch the needle movement

You do this test with the TPS unplugged and the car off

You're looking for a smooth sweeping motion of the needle on your meter

You set your meter to something like our times 5K or are times 2K

If at any point while your meter is measuring and the needle is interrupted you've confirmed that the TPS is faulty

No plug the TPS back into your harness and go back to the front of the engine

With a stick pin probe the green wire physically bypassing the stick pin through the conductor
Switch your meter to DC volts and the maximum voltage you are working within his the 5 V DC scale

Picture red lead to the stick pan and your black lead to battery ground
Start your car up and you should see about one volt DC within acceptable range of .7 to .9 volts DC at idle

Anything from .59-1.27v's at idle should be fine and 3.5v's above idle at wot.

My cougar was sitting at 1.25 volts for a year or two before it finally through a tps code. Im pretty sure it was the original with 320+k miles on it.

Key on engine off, 1987 bird codes.: http://youtu.be/z0ehA8cFTkc

Test ran by yours truly using a paper clip and an old school buttstuffog meter. You can use a test light or a sound buzzer if you like. It litterly takes 2 minutes start to finish.
