While recently having my idler pulley replaced at a 5* Chrysler dealer they recommended an engine decarb and I passed thinking I can do this on my own after reading about it here. Yesterday I purchased some Berrymans B-12 in both aerosol and liquid and was wondering what would be the best way for me to go about this. I will be changing the oil after I do it too. I just don't want to foul my plugs. I was thinking of removing the intake hose and spraying the aerosol in the TB throat under a 2000rpm idle and pouring about 4oz of the liquid through the vaccuum line. Any recommendations? The car has the 3.5L HO V6 in it.
DeCarb recommended for my '01 LHS

Remove your spark plugs and do a piston soak. Do not pour any liquid into the engine while running!
Sprying into the intake manifold in short burst while reving the engine is a much better idea then pouring it in!
If the vechile has been maintained and you are not geting any detonation or run-on I doubt you really need to de-carbon your vechile. Do not use the red spray tube with the B-12!! You would probably be better off with Amsoil Power Foam sprayed through the intake while running and running a dose of Auto-Rx to clean up the internal of all lubed surfaces. Periodic fuel system cleaners like SI-1, QuickSHot, Techron etc... a few times a year are also a good idea. The areas that usualy get carboned up can not be reached with the methods you are considering. Idle Air COntrol and EGR passages usualy require removal of the componets and directly accessing the are with the solvents and flexable scruber.
The systems used by many OEM use a mix of gasoline and solvents sprayed directly into the engine via a special orfice that goes betweenthe throttle body and duct work. They usualy remove fuel injector relay and run the car on this external mix for about 20 minutes. Then they use a low presure flush of the fuel rail and also spray the EGR area with a special adapter plate. They do not do it like freq. described on this site.
Many have had good results by useing Fuel Power every fill up. Their is no risk to useing FP at all!

So do you think I should just do a couple bursts of the aerosol in the intake tubing while revving and just not use the liquid?
I maintain the vehicle very well(I think) and run a bottle of Techron FA at every oil change (3500-4500miles) Is it okay to put the liquid B-12 in the gas tank then as an alternative to the Chevron stuff?
Thanks for the input!!!

A quick word of advice that JB touched on. When spraying DO NOT use the extension tube. It can get fired into your intake like a missle. Yes, this is th evoice of expierence
My airbox has an upstream removable silencer that would give me a great opening to spray into...is it okay to use that or what about the opening in the intake tube that leads to the manifold vent tube? I could temporarily pull that line and put a push in filter on that while I'm spraying could't I?
I would use the Mopar combustion chamber cleaner and follow the instructions, its powerful stuff. which is spray it in the TB while its running, use the whole can and then turn off the engine, let it sit for a while, I like to let them sit for several hours while I work on other things, then start it up and you get a **** of a smoke show, drive it around in 1st gear hard and let off the gas, give it more gas, etc.
I work at a 5 Star dealer and have never seen anything like this stuff, works great on rusty bolts/parts too, we use it for all kinds of things
think its like 6 bucks a can
