Combustion Chamber Cleaning
I am trying to decide whether or not to have the dealer perform this service. A few years ago, I did performance tuning and we used to do that type of service. There was a chemical we used that was pulled into the intake with vacuum. It would smoke like heck and would clear and the difference in power was amazing. I've heard oldtimers used Marvel Mystery Oil and the latest was warm water that posted fantastic results in eliminating engine ping by decarbonization. Has any tried this with a late model F150? I am particularly worried about the up-downside O2 sensors...

I've done it on my '97 4.2L with good results.
I can't remember the brand of the chemical, but I hooked up the can below the throttle body, in place of the PCV hose.
It stopped the engine pinging, but I didn't feel any power difference afterwards.
If you're concerned about the O2 sensors (valid concern), just remove them for the procedure.

Great idea about the O2 sensors. Thanks for the info. It's appreciated..

I suggest using a combo, intake cleaner and fuel system cleaner for best results.
I have had success in using SEAFOAM and Chevron Techron.
Also Amsoil Makes a similiar setup Called Power Foam, and PI (Performance Improver)
