stutter?
Guys I been having this stuttering problem since the begining of the new motor. The car will constantly stutter if you dont give it enough gas. At cruising speed (steady on the peddle) it will stutter like no other. I notice after I boost a few times or when its really hot outside it goes away. But sometimes it is still there. If I give it gas acclerating there is no stutter. I am not sure what it can be. I am running a stock gsr dizzy, nologly hot wires ( I tried ngk blues and same prob). bkr7e spark plugs, hondata s300. I noticed on the datalog when it stutters the duty cycle, fuel, and tps drops to zero. and turns green. any suggestions would help. I tried fixing the voltage on the tps. But it jumps around alot so its hard to get it perfect.

Re: stutter? (litovi3tboi503)
TPS sensor voltage is very unstable. Jumps around alot. when i set it at .45 and got it steady for a little i did wot and it reads 6. It is still not steady at wot. When I set it at 4.5 and drive the car then come back and check the voltage again its either in the .3's or .5's. its weird anyone know whats going on? bad tps?

Probably a bad TPS. Try checking how the voltage increases while you open throttle on the TPS. I believe its supposed to be a steady increase. Do you have any CEL's? TPS CEL is 7 I believe. Good luck!
