I've been reading a couple threads about this on the 3rd Gen Forum with positive interest. In short, gradually adding water to the engine while it's running can help dissipate a lot of the internal carbon buildup. Does anyone have a good method to share for this? I'm assuming I'd want to add the water past the throttle body, somewhere on the intake. Not sure what is the best place.

I think if we were to get some pictures and a short write-up going it could be very helpful to a lot of people. I did some searching and there aren't many threads on how to steam clean the FC.

 

Its no different than adding seafoam to the engine, except cheaper

Just yank a vacuum line and let the engine suck it in, but not enough where it stalls it..........or hydrolock it like i did once on my daughters truck on accident

 

Fair enough.. I'll give it a shot after work.

 

Ive done, water, sea foam, and zoom cleaner. They seem to have similar results, although zoom cleaner is mazdas product to do the same thing.
