My wastegate solenoid was buzzing on me so i decided to finally change it, i removed the intercooler piping and seen all the soot in the intake so i carefully cleaned what i could see trying not to drop any down. i put everything back together no problem and the truck will crank and stumble a bit but wont run, so i put the old solenoid back in and same thing. throws a p0069 code but i checked the intake and its clear right to the turbo. not sure where to go from here? :shrug:
