This is my first time posting here, so please excuse my language. I have a 99 Dodge Durango 5.9L 4x4 that I love. I purchased it with about 54,000 miles and now it has 184,000 miles. I recently made a trip to Florida with my family and that is when the problems started. My "dingo" started experiencing hesitation problem. The dingo wanted to stall when we drove it in the heat. It would cut out once the temp got to optimal temp or in stop and go traffic. Changed out the coil pack, the distributor cap and the pickup coil. Once I returned to the cooler mountains, things got a little better, but now I am having a battery temperature sensor code and my gas guage and oil pressure guages are fluctuating. But the oil pressure doesn't bottom out. Dingo doesn't seem to be effected by guages, but is concerning to me. Can anyone help me with what might be the problem.

 

Could be your ECM overheating, put a bag of ice on it and see if this still happens.

 

+1 on that!

Also if the battery sensor is bad it will do many strange things. You might need to replace the sensor but most likely I bet you need a new battery.

 

+1 Battery i just put a new one in mine

 

Thanks guys for the help. Had the battery checked and it is in great shape. Had my brother-n-law run a code scanner(former mechanic) on the Dingo and he pulled three codes that didn't show up on a small ODB scanner. The codes were P1595, P0125 & P1490. I am in the process of replacing the battery temp sensor to take care of the code that was showing up on the first scanner. Does anyone know if these additional codes could possibly cause a intermittent stall on the motor or cause some of the gauges to fluctuate? Had a few hesitations in Florida and another about a week ago. Stalled and then started right back up. Wanting to cross everything off the list before I go and drop the tank to check the fuel pump. The occurrence doesn't happen often. Any help would be great.
