Alright I just tried adjusting my TPS sensor on my 89 5.7L TPI and its not even close to what the haynes manual says. I jumped the wires and stuff and its supposed to be around 0.54 volts and im reading 4.98 volts.
Also how can I tell if my IAC is still in good working order??? Im wondering if that has anything to do with my 600 idle.
