The TPS on a SE is just 2 stage right? It's either "on" or "off"????? Or completely bass ackwards...0 Ohms to ____ Ohms?

Nope, the TPS is a gradient linear potentiometer that tells the ECU where the throttle is at any given time.

The TPS must be set using a 2-light fixture (search on that and TPS for more detail) at idle with the engine off. You can alternately use 2 ohm-meters, but that is a bit harder to do. The FSM will list the correct values for WOT and idle, but I don't have that in front of me right now.

Is the car having a problem that you're trying to diagnose?

all i needed to know. Just still trying to diagnose my lack of power after half throttle. Used Ohm meters before and worked great. But went to radioshack today and bought two 12V DC light's with wires and am going to wire up a TPS adjuster

It's simple, it's quick, and it's cheap - these are all big points in my book!

My 2-light gizmo actually sits on my workbench in the garage so I can check on stuff whenever something seems to be going astray.

As to the loss of power, what exhaust do you have on there? The stock system is 20+ years old now, and the cat may well be clogged or internally broken which can directly impede high rpm power through exhaust gas restriction.

Might also want to check for smooth operation of the AFM door - remove air filter lid and use your finger (or a wooden stick) to move the AFM door from full stop to full WOT open. If it has any 'sticking' points, it may be hanging up when you get over a certain RPM, thereby limiting the computer into thinking that you're getting a much lower airflow than then engine needs and therefore, limiting the fuel input.

Let us know what you find - I'm sure someone has had this and solved it,

in my sig. is what i've installed..
