stalling

This sounds like the TPS or throttle position sensor. You could try buying it at an auto parts store that you know you could return it if that wasn't the problem.

Good luck

Most likely TPS as ALS85GT noted, but I would also check your radiator cooland first...I have seen that cause similar behavior, but usually so dramatic.

Thanks.

Tell me all your mod's.
