TPS adjustment

ok.... i've looked everywhere, how can i adjust the TPS on my N/A 87 rx7? it's gone stupid on me... please help!!! :(

why don't you try your search engine, how can I use it anyway's, can't seem to figure it out.
The TPS is the black plunger in the center. The screw in front of the TPS is used to make adjustments.

The TPS is part of the Fuel and Emission Control System. It has two major functions: To cut the fuel off when you snap the throttle shut from wide open throttle. (This prevents backfires...) And the sensor also tells the ECU the position of the throttle body. This allows the ECU to make adjustments to the air/fuel mix at different throttle positions.

Most common signs of a bad TPS is a car that runs rough at Idle or a car that has a hesitation problem during acceleration. Bad backfiring could also be a TPS, but backfiring is usually caused by having an aftermarket free flow exhaust.

NOTE! There are two types of throttle position sensors. The 86-88 cars have a single piston TPS, the 89-91 cars have a dual piston TPS. The 86-88 sensor is not inter changeable with the 89-91. However they are adjusted exactly the same!
you're car has a single piston located in the black plunger in the center, hope it help's.for more info go to http://home.rmci.net/panther/tps.htm
