Apparently, my 5.4 needs a little work and the dealer is wanting $179 for a Fuel Cleaning which includes:
Fuel Injector Cleaner
Intake Valve Deposit Cleaner
Air Intake Cleaner
Does this seem worth it to anyone compared to buying the pour in liquid cleaners?
Air intake cleaning:
Undo several screws under hood, remove the intake, and just clean it with whatever, like a baby wipe or something. It is highly unlikely that it'll be nasty or difficult.
Spray some MAF cleaner on the sensor while it's off. Easy.
5.4 tritons don't get CBU issues like some modern motors, so it won't be a mess or a challenge
Injectors:
2 bolts to pull up fuel rail and they can be unspected, they just snap in place.
If there's a serious mess on the spray tip you can just let it soak in a variety of $3 - 10 injector cleaner additives. You can also, afaik, apply a 9v battery to the contacts to make it spray and observe if the pattern is good. Maybe manually feed some injector cleaner thru it like that (NOTE: serious eye protection needed and don't get that on your skin either, it'll eat away at your skin)
Intake:
for that money they aint taking it off an soaking it or walnut blasting....and it probably doesnt need anything like that anyway.
Theyre charging you to have a technician pour a bottle of fuel system cleaner in your tank methinks.
