decarbing?
We own a 2001 Ford Explorer . Recently, we brought into our local Ford dealership for an oil change. They told my wife that it was due for a "decarbing". Can someone tell me what this means exactly ? Thanks in advance.

I might be way off base here, but I'm guessing that they mean decarboning the combustion chambers. I did this myself in the driveway with 3 cans of pm-3 from the ford dealer and a section of vacum hose about 2 feet long. What you do is replace the vacum hose on the throttle body with the length of hose. With the truck idling, use the tube to suck in about 2/3 of a can of pm-3. Be careful that you don't stall the engine, go very slowly. After the 2/3 can has been ingested, let the truck sit for an hour or so. Then suck the rest in and drive with the RPM's around 3k. There will be TONS of white smoke out of the exhaust. Then repeat the procedure 2 more times. All totaled it took about 5 hours for me to do this on a saturday. Here's a link to the TSB.

Your dealer is full of it. Fuel injected vehicles don't need to be decarboned unless they have been driven a fair amount of time with bad oxygen sensors or bad injectors - in which case you would have been driving with the check engine light on.
Another scam by a crooked dealer in my opinion.

I know some people who work at the local Chevy dealership, and they try and sell all their customers a decarbonizing job. It's quick cash, but in the mechanics opinions there, the cars don't need it unless they're having rough idle issues, and other small annoyances that can't seem to be fixed. They arent the ones selling the customer the job though, the guy that schedules the job is the one who tries to sell it to everyone.
