92/92 are the same, and 94/95 are larger, and require a 94/95 intake, or */C

The only two sensors on or in the TB are the TPS and the MAF. Both should be interchangeable between 92 and 93, but I wouldn't use one that old if I needed to replace one.

You used CARB cleaner? That'* bad news. Wrong can.

And never do anything like this to your TB without removing the MAF first.

Now i know but it might be too late. If i can find one for cheap ill go ahead and buy it thats why i need to know what all will work with that car. I dont know if thta one is bad yet is there any way to test it? along with the tps. Where is the tps sensor located, is it the spring on the supercharger side of the inner throttle body, would getting that part wet with carb cleaner ruin it?

Only a 92 or 93 MAF will work for you.

A 92-94 TPS from an L27, or a 92-95 TPS from an L67 should fit.

The TPS is hermetically sealed with potting compound. I doubt any damage was done by the carb cleaner, unless it was to the plastic outer case, and that should be visible. Check the connector to make sure there isn't some juice in there.

Both the MAF and TPS failures will cause obvious performance issues. Your cruise control may not work right, throttle response will be iffy at best, and you'll run too rich or too lean. Are you observing any of this? Do you have an SES light?

NEVER use carb cleaner on an Throttle body of a newer car. Carb cleaner is for carbs, intake cleaner is for intakes and throttle bodies. Always remove the MAF sensor before cleaning, and remove the TB from the car to clean it, or you may be wasting your time.

THe tps should be fine. I never sprayed the plastic covers, i just might have gotten some carb cleaner on the maf sensor in the inside of the tb.
