my car idles at 400 rpm ,and if i turn up the idle adjustment screw it will jump up but then i think the computer recalibrates the idle and it drops right back down..
can i move the TPS and make the idle go up for good?? what will this hurt??
i really could use some help here guys, a low idle with forged pistons sucks!!!! it makes then rattle louder because it is about to stall out.

i remember hearing something about cleaning a valve or something on the bottom of the throttle body ,,will this help?? more info please

Did you check for vaccum leaks?

 

yes i am still holding the same amount of vacuum that i use to, all hoses are ok.
anyone else??

 

what is your TPS voltage at idle?

 

i dont know that right now, i only have the 2b, and no type of a piggy back, i just took out the vafc, so i no longer have reading anymore??
