Hi all, new to the site. I have a 1999 Jeep Cherokee sport 4.0 automatic 4x4 with about 130,000 miles on it all stock. I am the original owner. I am getting bad map sensor codes 0107 and 0108 (low voltage, high voltage) also had a no voltage code. After the vehicle warms up it runs very rough almost to the point of stalling. When driving at speed it jerks (like fuel is cut off for a fraction of a second). I have replaced the map sensor and the crank sensor no resolution. Took it to a local mechanic and they couldn't fix it, said it might be a bad PCM. Any help or suggestions would be very appreciated. I love this vehicle and want to keep it going.

 

Inspect every inch of wiring for the map sensor circuit.

 

Will check all wiring, thanks for the advice.
