Seafoam is the shizzle.

 

Seafoam is great stuff!

 

if it didnt help, obviously you had some more serious problems with the motor that a simple additive can't fix.

 

There is no such thing as 'God In a Bottle' if you have a mechanical issue, ain't nothing in a bottle gonna fix that.

 

as i said, some carbon is necessary in old engines. i was hoping to get away with valve seals so i seafoamed it to see what would happen. the stuff works. just don't use it on an engine with high milleage unless you know the engine was well cared for. as a fuel additive i've been told it can eat o-rings so use it lightly in efi engines.

 

You can get Seafoam at AutoZone, Napa, and some Menards

 

Will Seafoam harm the 0-2 sensor?

 

it claims not to on the bottle.

 

Water trickled in the intake will do just as good of a job removing top end carbon as anything else:
