I just finished my build, the car will not run with the map sensor plugged in. If I un plug the map the car runs but idles around 1300 rpm. All the items listed in my sig are part of the build. What is a good starting point to get the car to idle with the LT4 hotcam?

 

I checked voltage from map and tps. I am only getting .65 volts

 

Look for a pinched wire. The +5 volts goes to the MAP sensor and the throttle position sensor (TPS).
