As most of you educated 3rd genners know, the 90-92 TPS is not adjustable on the TPI motors (don't know anything about the other motors). I was wondering if an 89 adjustable TPS would work if I bought one?

 

I'm somewhat uneducated , but my '90 setup on my 406 has an adjustable TPS............maybe it's an '89 part but if so it should work.

 

My 90 is not. I just replaced it with a AC Delco and its not either ?????????? hum

 

The SD computer will see were the TPS is when you turn on the key and compensate for the reading, you do not need to adjust it.
You can use the 89 on the car but it is not needed. When I first got the Z I tried to adjust my TPS, I just made the bolt holes bigger and did it that way. Jump forward 3 years and the TPS got a bad spot in it, so I got a new one and put it on the car, it reads .63 when I turn the key on, but the scan tool shows 0% at idle and at full throttle it is 99.6%.

 

My tps on my 92 is adjustable. It has the slotted bolt holes.
