|Jerry Bransford||Cleaning the throttle body's interior is something that should be done once in a while because it does get grimy inside from combustion byproducts, I do mine probably every couple years. $7-8 for an aerosol can of throttle body cleaner (3M is a good brand but any major brand is fine) is all you need. Directions are on the can but basically you just start the engine after removing the air intake tube and while keeping the rpms up a tad, empty the can into the throttle body intake. Maybe half-way through the can, kill the engine and with a cloth & cleaner, clean the backside of the butterfly valve after opening it fully with the throttle lever. After it's clean, re-start the engine and empty the remaining contents of the TB cleaner into the TB which dissolves the grime so it can be burned up in the combustion chambers and then blown out the exhaust.|

Good to know . . . thanks for posting this up.
Does this include cleaning the Trottle Body or is that something to look into?

|Jerry Bransford||Don't bother. That service is a HUGE money maker for dealerships and they push the crap out of it, it's like 90% profit for them. More importantly, your Jeep doesn't need it. Clogged fuel injectors are pretty much a thing of the past since the gasoline producers finally started including enough fuel system cleaning additives in all grades of gasoline.|

Dealership recommended fuel-system service
I've got an 05 TJ with just over 60K miles on it, and at the dealership for the service they recommended a fuel system cleaning ever 30K miles saying that it would improve performance and remove carbon buildup. I'm looking to do more of the services myself to save money, but I'm a newb with tools so I thought I'd let the pros handle the t-case and diffs this time.
This seems to be slightly bogus to me, but for the more knowledgeable folks on the list, what exactly is it the dealership does for this service? Is it simply a fuel additive like injector cleaner? Are they cleaning the AIC or throttle body?
