any body know tps voltage @ idle, should it be around .5? also i put a bbk throttle body on and it will not idle any input thanks.turned it up 3 turns already. thanks for every bodys help with the last problem.

 

Take it off look in the back and see if it has a hole for the IAC Valve.. i bought a holley last year and i had the same problem found out that there was no provisions for the IAC valve to allow air into the intake when the throttle was closed.. the car would either run @ 1000 rpm or no idle at all

and yes the idle throttle voltage should be between .3-.5

 

thanks man could bee, dosnt sond like iac is doing anything. another problem im having it starts rite up , if i make it stay running as soon as it warms up it shuts down. i dont know whats up with this car
