Well, I guess mine blew out really badly because the engine is so erratic. Perhaps there are more problems then one kicking off. If I could figure out how to post a video Id show y'all. For the thermostat, how many degrees is a safe economical temp? I also may have some kind of engine or transmission mount loose. Its squeaking pretty bad. Which may explain the wobbly engine. By chance, are all of these common problems written out somewhere because I think I have them all. Im gonna pull the codes again and get them up. Just replaced the throttle position sensor and it had no effect. Also amongst all this the AC quit blowing cold. It has 116xxx. If this engine becomes junk Ill probably look into finding one of those old diesel trooper engines and make some biodiesel to run it.
