Mopar combustion chamber cleaner is the best product I have used for this. 5 dollars a can at the dealer. You get a nice warm (operating temp) engine and spray this down the throttle body as fast as it will take it. Then immediatley shut it off and let it soak 15 minutes. then start it up and be ready for some smoke, I mean a lot of smoke...........
Any FI cleaner cna be used through intake?
