Title: Truck smokes leaves black soot
Post by: 80silveradosurvivor on June 06, 2016, 03:32:26 pm

I just started my truck after it sitting for some time. It smoked for a good while and left a bunch of black stuff on the ground behind it. Its almost like oil. Its a 350 stock with a Qjet. Thanks in advance .

Run it for a while and see if new, fresh fuel helps.  If not, clean up the Q-jet and install carb kit with new needle/seat and gaskets.
