If 4.0L in line 6 does not use MAF has a MAP. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

4.7 liter, I have taken the jeep to the dealership repeted time for the same problem, still unresolved. The jeep doesnt want to start, the strater seems fine, according to the dealership fuel system checks fine, the replaced the iac motor and the battery and I have replaced the starter and throttle position sensor. On your websites advice I subscribed to mitchell on demand, but, I cant find the location of the map sensor for the 4.7. Then again im not able to navigate very well. Could you please direct me on the eautorepair. Net to the diagram with the loaction of the map sensor for the 4.7 and give me some sound advice on the istarting issue.
