Should I go to Jiffylube and pay $40 for the fuel injection cleaning service or should I just buy a bottle of additive and do it myself ? Ive seen them do the service and it basically looks the same unless I missed something.
Buy the black can from your Ford dealer. The only injector cleaning service worth it (IMO) is when they pressurize the fuel rail with the cleaner. If the Jiffylube folks will do THAT service, then it's worth the $40.
You are so right about pressurizing the fuel rail. That is well worth having done and if it's been a while, you may find quite a noticeable improvement in performance. I did.
yeah Jiffylube does it some other way like unplugging the brake booster vacuum hose and feeding the cleaner thru there. Sp I guess its basically the same if you were to just add the treatment to the fuel tank.

And this cleans the INJECTORS how? What you describe seems more of an lower intake cleaning (valves) to me.
