Most people seem to agree that the trash is the best cure.

JUST PUT another return spring on it. problem fixed.
.25c fix.
not all of can afford the $400+ fix of replacing the TB.

The shaft coming out of the TB that goes into the TPS is too short. i put my car together and went to dyno it. it kept jumping timing to 34* half way thru the run. we dynoed it many times trying to figure out what was doing it. we thought it was a tunning problem. The TSP showed 100% at WOT and 0% at idle just like it should so i didn't think it was that. Just out of no wherei put in a new TPS and poof it went away. i was happy .
BUT then on a HOT TEXAS summer day while i was at the track at the end ofthe sixth or seventh run my motor detonated, knoched a chunk out of #7 piston and cracked the cylinder lining. I had accidently left 87 octane in it that day and thought that was what blew my motor. But after i get a new motor and have everything perfect go back to dyno it again and it is STILL doing it! The TPS was reading 0 % at idle and 100% at WOT so no one thought that was the problem, hell it was a new TPS. But as i sat there on the dyno i SLOWLY started to give it some throttle and it would be at 2,500 rpm's before the TPS would read any change. I thought it HAD to be the TB. Put in a TPIS 90mm and now as soon as i touch the throttle the TPS registers right away. and no more jumping to 34* half way during a run.
Turns out the shaft is too short on the FAST and it doesn't reach far enuff into the TPS.

that is some crazy **** for sure. I wonder if this is a recurring event with the FAST 90's?
