De-carbonization

Hi there once again

I want to perform the de-carbonization process but I have a question. On alldata it states to uses Carburetor cleaner aersol part number Pm-2 and Carburetor cleaner liquid part number PM-3. I went to my local ford dealer and all they had was Tune up cleaner aerosol part number cxc-52-b and carburetor, choke, and combustion chamber cleaner part number cxc-53. Are PM-2 and PM-3 the same as my products or should I find the right PM-2 and PM-3?

Thank you

Did alldata give a brand name?

I called a few ford dealers and PM2 and Pm3 have been changed to CXC-52B and CXC-53 so these are the same products.

Why bother with OEM cleaners? I've never seen an off the shelf spray or liquid cleaner not serve the same purpose.

Can anybody give me the steps or have a link on how to do this? I would like to do it to my 1999 windstar and see if it makes a difference on the mileage it gets. When complete, is it possible the crudd that gets cleaned out may damage the O2 sensors? I just put new O2 sensors in this summer and do not want to damage them.

Weedman, on my 2001, I periodically idle the van, pull the PCV valve out of the valve cover and spray a cleaner thru the suction end of the PCV valve. The engine will stumble a bit and may stall if you get too aggessive with the spray. I have also removed the rubber bellows closest to the throttle body and sprayed out the throttle body (with engine off). *knock on wood*, I bought the van 3yrs ago with 34Kmi. Have 70Kmi on it now & never even had a check engine light. Never had the upper intake off. Atleast since I've owned it. Oh.. I buy the least expensive, off the shelf, sensor safe spray cleaner I can get.

I work a a ford dealership and we wont even use the ford crap - the original part numbers you have were great - the replacements are "eco friendly" an don't work - hit the parts house and get a cheap carb/choke cleaner and you will have better resuslts (the cheaper the better - they are still "eco unfriendly" and work) as for the O2 sensors you will be ok - best be is to do this on as cold and engine as possible so you don't overheat the O2's when you blow the cleaner out and when they warm up they are self cleaning.

.. hit the parts house and get a cheap carb/choke cleaner and you will have better resuslts (the cheaper the better - they are still "eco unfriendly" and work)...

Thanks rivguy. I often wondered about that. I used to buy the name branded "Throttle body cleaner" for "fuel injected vehicles", etc.. until I looked at what they contain. It's basically the same stuff as a $0.99 spray can of carburetor cleaner! Any more I buy the least expensive carb/choke cleaner I can get and be done with it. The marketing gimmicks associated with these cleaners is amazing. :banghead:
