OK, here's my story. Drove my 760 turbo home from seattle a week ago, had no problems. Went ot get it deq'd today, about 15 miles on thwe freeway. About a mile from the deq I was stopped at a light, when light turned green, car didn't want to move, I had to depress accelerator about halfway to get it moving. Get to the deq, pass with flying colors. Leave the deq and it doesn't want to go again. I got it all the way back home, but the turbo was used almost all the way to keep it moving. By the time I got home it sounded like it was running on 2 cylinders, and smoke was coming from the rear of the engine. What did I do, and what do I check? I am terrible at troubleshooting, but can fix almost anything if I know what it is. Please give me some input. Bob
