How to adjust the TPS?

[Steves87]

Still new to the GN world and have my ScanMaster hooked up and need to adjust the throttle position sensor. I know it is located on the trottle body, but where and what does it look like? For that matter which way do I go with it?
I read it is a set screw, but I don't see any adjustable screws on the TB. I searched and came up with adjusting it up or down will help the idle #'s and back will adjust the WOT #'s. Is that right?

It's located on the passenger side of the throttle body just past the upipe. It has two screws that must be loosened simultaneously, then you can slide it up and down. Good luck, it's rough entering the TR world without gnttype.org. Hopefully it will be back up soon as there are plenty of good diagrams there.

Thanks guys, that helps a lot. Should I adjust while the car is running or shut down?

Turn the key to "Run" but, do NOT start the engine. This is from the link I posted...you probably didn't have time to read it all...
