I was told to get my tps voltage to .7 by alvin at pcmforless.com so i could get some good datalogging. My tps voltage was .3 at idle and was causing all sorts of problems. The bes tive been able to do is 1200rpm park idle and a 750-800rpm drive idle with my tps at .61 volts. are those rpms to high for my car?...1200 seems alittle high, but my drive idle seems right on the money..i think my target is 900rpm according to my datamaster..

the reason im having so much trouble is because of the cam i think...the idle is totally different from the stock settings. I verified this when i put the stock throttle body back on and fired it up. The idle was wayyy high so i had to punch out that cap and adjust the idle that way..thus lowering the tps voltage

 

woooooow nvm i got it..took alot of fine tuning and reviewing but i finally got .7 at ilde with an 800rpm drive idle and 1050-1100 rpm park idle

no more stumble, stalling as i come to a stop

if anybody is having a problem...ask me ill help you out

 

yeah i need some help with my idle after i changed my cam, check out my thread titled "low and unsteady idle". if you can help me your the man!! haha
thanks

Base TPS voltage should be no more than .58 volts at closed throttle and no more than 5 volts at WOT. .60volts is actually pushing it for a base TPS voltage. Your base idle sounds ok though. With mine set at .56 it runs at 800 base and in gear drops to 500 rpm...Nice low RPM to hear the cam.

MAP cars use a .6-.7 voltage at idle from what im told...maf cars use a .5
