just bought a 96 2wd sport, 5.9 auto, runs great but sometimes at an idle will stumble, also seems like temp guage is crazy, will be around half way then go up and then back down, fan clutch feels good and radiator feels cool,confused, all new to me, love the truck though,thanks, Lee

 

Hey welcome to the board. I'm a newbie too. Great truck so far. I have changed the o2 sensors and changed out the thermosat because of a temp code. So far so good.
