"slow" people lol that would be great,, thanks alot,, Jayson
You can do the Chinese water torture/Seafoam treatment anytime during the engine maintenance process. Just be sure to do it all; TB, plugs, sensors and their connections, etc. Here is the description of the process I sent to the moderator.
Please note that you can get the Fire department called on you doing this. It has happened!
Here is the technique:
Engine should be fully warmed up.
Connect an 18" vacuum hose from a vacuum port above the throttle. I used the one going to the charcoal canister.
Take a jar (normal size mayo or spaghetti sauce jar) filled with (distilled)water (this would be just under 4 cups)
One hand holding throttle open so engine remains in the 3 to 4 thousand rpm range.
Dipping hose in water over and over approximately once a second for about 1/2 (0.5) second or less, less often if engine slows significantly, engine will run rough so use throttle to maintain engine speed until all the water is gone which will take only a couple of minutes more or less.
Repeat with the 16 oz can of Sea Foam Carbon Cleaner (SF16, UPC#: 1881200001) (or GM Top End Cleaner).
Remain alert and focused and just donít let the hose stay in the water/fluid for much more than half a second at a time and you should be safe. You know you are feeding in too much fluid if the engine speed drops signifaicanly even though you are trying to maintain it with the throttle. Be prepared to see a lot of smoke from the exhaust and from the exhaust manifold. This is normal.
It is best to let the car stall while sucking in the last amount of cleaner. Let the car sit for about 15 min. and then take her for a high rev drive. Put her in 2nd and get the RPM'* up around 3500 to 4000. Drive around until there is no more smoke or about 15 min.
This procedure will not harm the Cat, O2 sersor or any other components. It can be done at anytime. I have not seen it but GM does have a version of this procedure as well as the carbon cleaner.
