I just replaced a v6 motor in a 1993 chevy s10. I am having problems now after 2 days after replacing motor, far as engine idling high. I had three things in mind, first thing was TPS, second coolant temp sensor, and third the auto air control. Now I unplug the temp sensor it wants to idle way low then idles way back to high. With it unplugged it will not start at all, I plug it back in, and I unhook the TPS doesnt change anything. Far as the auto air control to. What could my problem be? I was told the coolant temp sensor can affect the idle speed. Its making transmission shift hard and takes longer to shift into the gears. Can anyone help me out on this?
