I can agree with that.
I have used seafoam in 2 stroke outboard motors for years by adding it to the gas and I have torn down many motors before using seafoam and after using seafoam in them and the difference is astounding at how much it cleans the carbon out.
After seeing how well it worked on those I also started using it in my vehicles.
The adding it to the tank works better imho because it doesnt foul your plugs and it removes the stuff slowly and not in chunks that could possibly take out a O2 sensor or cat on a vehicle.
I run one can a month thru all of mine.


I would start by changing your plugs to see if it improves your condition any.

 

Y'all do realize running a water injection system cleans carbon to... :}

 

Yes. That is how we cleaned carbon out many years ago. The point I was trying to make, is that there is a consensus here on the forum that you have to pour lots of Sea Foam down the intake. It is not a good practice and unnecessary. It is much simpler and easier to just pour some in the tank and drive.

 

Ok It started right up this mourning with no hesitation. I did not know that you had to take out the o2 sensor especially since the bottle says its safe. Anyways, it's been running pretty good but i might take out my spark plugs tomorrow just to clean them off, same with my o2 sensor. What should i use to clean them and how do I go about doing it?

also, there is a loud noise sometimes when im idling but it sounds like an oversized tea kettle not really a hiss. I think it is loose intake manifold bolts

 

some carb cleaner on the o2 and wipe it off, a wire brush on the sparks, or scrape em off with a knife. You don't HAVE to take the o2 sensor out, I've done cars with out in the past with no problems but lately I've been doing it just as an extra precaution.
