sounds good, where do i get it at? should i clean it with the parts off the car, or wait till i get them back on so i can start the car and let the stuff clean the pistons as well because im sure they have buildup too. thanxSupra_Class said:Use Mopar Combustion Chamber Cleaner. It's dealer item only & runs about $8-9 a can. 1 can should do it. This is the strongest stuff I have ever seen. A friend had major carbon build up on his pistons, intake, etc. used MCCC & cleaned it right up. Reg Pepgirls TB cleaner wouldn't touch it. I even used it on my Supra by running it through a vacuum line off intake manni. with engine running. cleaned up my carbon issues. Slightly improbed throtal responce & increased my gas milage.
