I have a 2016 GMC 2500 HD and just did a 'tune up' on it. Tune-ups today consist of new spark plugs and wires ($175) and sometimes new coils ($145). I started my little project at about 1pm and by 5pm...
I had to take the throttle body off of this little jewel the other day. What fun it is working on a Ford van! I never thought I would wind up a a Ford mechanic.
