Well I changed the fast idle a little to the fast side and thought I would see if it made any difference. Also changed the fuel filter. If I don't depress the accelerator it's not too bad with the smoke but if I depress the accelerator to set the advance and the fast idle look out it is smoke city. This has to give someone a clue as to what's going on here. I started to advance the timing a little to see if that would help but if when you depress the accelerator advances the timing and that makes the smoke worse would it be the same if you manually advance the timing or is it a different situation? I'm confused. I still think it is something simple because the truck runs too well and starts too well under warmer conditions. Could there be anything in the wiring harness that could be breaking down? What do you think?
