Hello I have 00 Durango that keeps cutting off on me while driving. At first I noticed it only happend once the vehicle was hot. Had to be 80 degrees outside or hotter for it to happen. Then it started cutting off whenever it feel like it! We have cleaned the Throttle body, replaced PCM, a red & black sensor, sorry im a girl dont remember what it was called! Something along the lines of ignition sensor? Previously had TPS issues, so thats new. A cooling sensor, because when i would start it, it would cut right back off. Had to hold the accelorator till it fully warmed up... so thats new. Check Engine finally came on the for the first time, but that was for a misfire. Replaced the spark plugs. The next day it came back on with a map/baro code. Had it checked mechanic said it was fine. Enigne light went off on its own. Ever sense it cuts off on me while driving no matter if im on the highway or regular street at least 2-3 times. What else could be wrong??

 

Verify functioning of the battery, you would be surprised by the weird codes and stuff that starts to happen with a tired battery.

 

+1 on checking the battery. Make sure the connections are all clean too.

 

+2 on the battery,

also holding the throttle open to start/run for a minute or two is a symptom of a bad IAC motor/valve

 

+3 on the battery, +1 on the IAC
