My idle screw is turned up high and the idle starts high, but as the engine gets warmer, it eventually dies. Also, I had to put thread lock on the idle screw to get it to stay in place, otherwise it would screw all the way in. Oh yea, I can turn the idle screw with my fingers, prior to the thread lock. I have heard many suggestions but I wanted to hear some solutions from people who actually know these trucks. Thanks

 

Well, I took it to a good mechanic and found out a bad fuel injector was causing the idle problem! Also, I had a bad vibration when the clutch was depressed around 60mph and up. It turned out to be the rear u-joint. Running like a champ now
