I looking at replacing my tps sensor on throttle body. Am icorrect that in 90 the sensor was non adjustable sensor. When i try to buy one it does not have the slotted screw holes for adjustment. There is another member trying to sell me one off a 91 that is slotted. All my research tells me it wasnt slotted on a 90. Ineed to know so i get the right one. Please help!

 

Go to rockauto.com, most of the time they have a picture. How much are you going to pay for a used tps? What does yours look like and are you sure it is bad? Will it not calibrate? Take the screws out one at a time and look at the one on your car, that is probably the best research tool.
rockauto.com shows the tps for my 88 to have slots, the one shown for 90 has no slots. Still check yours but looks like your reasearch is good.

About 50-55 bucks if memory is correct, get a new one not used.
