ok not sure on this

The 89- and 89+ have different TPS on the throttlebody.
Can i put a 90 plus throttle body on my 87?
The reason I ask is because I think my TPS is messed up and I have a spare throttlebody and TPS off my 90.

The 88- and 89+ have different TPS designs.
Can I put an 89+ throttle body on my 87?

Now that it's a bit easier to read,
I, personally, don't know.
How are they different? Are they completely different? Are the plugs the same? If the plug is the same, you should be able to make it work.
What makes you think that the TPS is junk?

code 51 and strange throttle response. I would have to take a pic of them. Basicly the spring and potenciometer(sorry spelling sucks) are situated in differant location on them.

Nah, then I think you're gonna have to source an 89+ sensor.
Unless the 88- sensor plugs in. Then I suppose you can use the 88- TB.

well pulled the old sensor off yah it was FUBAR no spring to it at all it just stayed where you turned it to. and it was the same as the one on the 90+ TB.
now i wonder where the hell the other one came from
