It happens. I've seen my TPS voltage shift upwards with heat first hand.HAITHAM said:I set my TPS voltage to 0.97, after a while when the car warms up it goes to 0.99
Is this normal ??!!
How would it make a difference? I thought the only thing the TPS did was determine the position of the throttle and establish the idle setting. Is there more to it?recovering5.0L said:there may be no performance gains , but what about drivability gains if you install a cam?
I have everything in my sig on my car (heads/cam/intake/blower). I've run my TPS across the whole range. Nothing but problems with settings of .97 or higher, wheather they be subtle problems at times or just down right pita problems like hanging idle etc. No difference in driveability, actually much better in the lower .9'srecovering5.0L said:there may be no performance gains , but what about drivability gains if you install a cam?
Hmmm(?). Maybe try the idle reset procedure (clear computer, etc), and after the idle reset procedure is done set the TPS to around .92 Also clock your maf meter (that's helped me before too). Best of luck to ya'recovering5.0L said:the reason why i ask is my car bucks and surges sometimes after i installled a b303. ive cleaned my iab and throttle body and set my tps to .97 its getting very annoying now. it actually seems like the car ran a little better with it set at .94
Ooops, sorry about my slang. Actually just loosen the clamp and rotate the meter so the electronics are in a different location (then tighten clamp of course). Sometimes the actual sensor may be in an area where air velocity is slower than elsewhere in that intake tract. So by rotating the meter you might get a better air reading helping smooth out your idle a bit. hthrecovering5.0L said:thanks! but how do i clock the maf?
