Well after I changed several items my truck still stalls out, only now it’s once in a blue moon. But now I have another strange, very strange thing going on. Few weeks ago I left for work and drove about 10 miles and my truck was blowing cold air, I stopped and shut my truck off and immediately started it again, my heater worked perfectly. (Remember when my truck acted like a ford and would stall out I would shut it off and restart it). So I drove it this morning and the heater set at half heat it blew unbelievably hot, it feels like a sauna in the cab. My temp gauge read normal. My mechanic thinks it’s the computer all along, even the reason behind the stalling. But I am afraid to spend that kind of money and not sure that’s the problem. This truck is just a back up truck for me and is not driven daily. Any thoughts???
