Alright, finally got a new set of TB on it and put err back together tonight. Went out to the spot, got about 10 good passes on a sitdown, then when it started to warm up the problem started re-ocurring. So, so far, I think i've narrowed it down to the problem happening when it starts to heat up. What do you think it could be? My buddy took his MAP sensor, I think, off his 929 and put it in place of mine on the left side of the TB next to the airbox, and his is good, and it keeps on doing it. I also checked to see if that sensor would work on mine, and it's the same part number as the sensor's of the F4i's......

Need help desperately.......

 

dude it's probably your stator not pumping enough juice you need to see hoiw many amps its drawling if thats the problem then just put a new on in there very easy. but i had that problem bought a new stator for 75 bucks put it in and it ran perfect.
