I would disconnect the TPS and all oxygen sensors, re-test, if it still does it, crankshaft angle sensors are common on that engine, and let me know.

I have disconnected all sensors but it seems as if it's a short with injector noid light connected light vary dim but I will ck crank sensor today. I can tell when car is going to start light gets bright but when I hit throttle it dies out.

I was thinking too, it could be a shorted injector causing the the problem, you can use this guide to test them:
Yes I change the crank sensor ck resistance on all injectors Right bank readings are 00.7 12.1 and 12.1. Left bank readings are 12.3 00.7 and 08.9 the 3.1 (Vin T) 0hms should be 12.0-12.4 so I'll change out the injectors that are not up to specs.
