I did a complete tuneup (everything) cleaned throtle body, fuel system service, truck ran great last night. Today runs rough at idle even stalls no codes. I have hooked up a scanner and all values look good. The truck has black plugs and black smoke. I have check fp, inj pulse, ect, tps, you name it I check it. I had no black smoke after work was done untill next day.
have the same problem?
