I have had the truck in my sig for less than a week. Yesterday and this morning I went to drive it and had a few problems. The truck had no power, wouldnt shift out of first (automatic), no boost was built, sounded like turbo wasnt even spinning, and when i got on the pedal a little it dumped very thick black smoke. The egt's rose pretty quickly cause i only drove about 1/4 to a 1/2 mile each time and they hit 750-800. The wierd thing is that the 1st time, i left it idleing, popped hood looked to see if anything was blocking air filter and then turned around to head home to look at things in the garage. It was just fine after i turned around, everything back to normal. This morning I parked it back in the garage, it sat for 10 min, i went back out and it started fine, sounded normal again. (i didnt take it out of park) It sounds to me like a turbo problem but i am new to all of this. Any help would be nice cause im 17 and just bought my 1st PSD and dont need to be dumping money into it in the 1st week cause something went bad. Thanks!
