Map Sensor
Just installed a new map sensor and I still have the same codes coming up and the same rough idle. How do I test the power going to my map sensor I believe that is my problem( not the sensor but the power going to it.) and how do I fix short of running new wires

more than likely it's not electrical. I'm betting you have a vacuum leak throwing off the sensor. Check the hose running directly from the MAP to the intake/tb for crack, breaks, loose fittings, etc.
Also check the rest of the vacuum system for leaks.
What year cherokee is this?
