My only experience with SeaFoam was during a rebuild of my 3.2 race motor. It was the ONLY product that could clear one of my piston squirters. I had tried everything, and a single drop of SeaFoam cleared it immediately. It is amazing stuff. Whether it will solve your rough idle, I don't know. I would go through the things you listed above deliberately, and give each change a chance to be eliminated as the source of the problem before moving to the next. Every time I've dealt with an idling problem with one of my 3.2's, the first place I started was the CO mixture setting. If that is off, you will spend many frustrating hours trying to isolate the problem. Confirm the CO mixture with a gas analyzer FIRST.


From SeaFoam's website:

# With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using Sea Foam in these various ways as fumes will be extreme for a short time.
# Pour 1/3 to 1/2 pint into oil crank case to clean rings, lifters, dirty parts and remove moisture.
# Pour 1/3 to 1 full pint into fuel tank to clean injectors, carburetor jets, fuel lines and remove moisture.
# Immediate Results: Smoother idle, increased R.P.M.'s better throttle response and improved performance. See label on can for detailed results for use in each area.

When Used Thru Injection or Carburetor

* Cleans carbon build up
* Cleans intake valves and pistons
* Gives smoother idle
* Cleans catalytic converter odors
* Cures hesitations and pings
* Restores power and pickup
* With warm engine running, SLOWLY poor 1/2 pint through carburator, throttle body or direct manifold vacuum line that will feed ALL CYLINDERS. Possible sources are P.C.V. valve or brake booster line. Turn ignition off. Restart engine after 5 minutes. Be sure exhaust is well ventilated. Fumes will be extreme for a short period of time.
* For use in injector cleaning machines, use 50% SEA FOAM and 50% fuel.
* Fill diesel filters with SEA FOAM to clean injectors fast.

When Added to Crankcase (Oil)

1. Frees sticky lifters and rings
2. Increases R.P.M.'s vacuum and compression
3. Cleans dirty parts
4. Removes moisture
5. Cleans PCV valve systems
