Gumout?

Does Gumout Fuel System Cleaner really work? I think my feul injectors are somewhat dirty (hesitation in 1st gear).

Do a search on the forum for "Hot Soak"

It is a little unorthodox and not something you should do every month or anything like that, but once a year might be alright. It basically burns off the deposits on the valves in a big blue cloud!

Hope that helps!

It does help, not anything that would be felt right away, but it does help. It really depends on what grade of gas you use and from where you get your gas: I mean the station not the brand, all gas comes from one source they just add their addtives then drop it in the stations tank. The older the station the worse the gunk and water is in their underground tanks.

Okay, I read the other thread explaining the procedure, but wouldn't all that burned-off blue smoke just be going through one's exhaust system?
It'll screw-up my converter's ceramic honeycomb catalyst structure, won't it? How will I pass inspection with a dirty cat.?used:

That's the exact reason you don't want to do it very often. Yes, it could cause damage to your Catalytic Converter, but the effects are cumulative, and once you go through the Hot Soak, just go dog the ever lovin' snot out of her, and clean those deposits out before the Cat has a chance to cool!

I do a hot soak about once every 18 months on my cars, and haven't had a problem!

If you're looking to clean your fuel injectors, then hot soaking wont do much. Don't get me wrong, I love SeaFoam, that shit rocks! But, to clean your injectors you need to add it to your fuel tank, not your combustion chamber. Hot soaking is for removing carbon deposits from your combustion chamber/valves.
