2001 Dodge Durango

2001 Durango for sale, it was running fine, until it wasn't. this is a tough truck, it hauls my 32' trailer no problem, which weighs 6500 pounds plus an additional load of 2000 just in my tools. I can't figure it out, 2 mechanics came out and diagnosed it for me, told me all kinda of stuff that could be wrong, their OBD meter brought up no codes so i can't figure it out. it will start but runs like shit as if it is running on half the cylinders. you need to stay on the had pedal or it stalls. i pulled half the plugs on the driver side and not one of them were fouled, all the suggestions point to my endless labor leaving over the truck and i haven't the time off energy to do all that. Which i will relay that indoor to whoever is interested in it. This was, and more than likely still is a very reliable truck, just needs a little more love than I'm prepared to give.
