Have you checked you TPS sensor???

Rx-7Blazin

yup with the home made light i checked and it red out fine

Try using a volt meter. I thought the light was just to check to see if it was still functional(not sure). Try getting a volt meter and setting the TPS so that it reads like 1. on it or something(might want to search or find someone else that can better expalin it). Just search "how to set the TPS" or something like that.

Or you can just tune it by ear. Just hold the throttle at about 3 grand(or right before the last point it stops(idle still jumps) and turn the screw till the idle evens out.
