Throttle Body Carbon Build Up?

hooey_b · 02-01-2016, 04:59 PM

I use Seafoam to clean out my fuel injectors and vacuum lines up to intake mani.

1-1.2 oz per liter displacement (so roughly 4 oz) fed in thru your brake booster line while running @ idle and normal operating temperature. Once you put all of it, cut the car off and let sit 10-15 min, then start it up as normal. Drive spiritedly to get rid of the carbon buildup being burned off.

No more than 5 -6 oz for your gas tank. Add while the vehicle is off, wait 10-15 min, then start car normally. Drive around and hit WOT a few times to run thru the injectors for the cleaning.

I do this roughly every other month, along with the TB cleaning, and it runs like NEW. (I'm at 139k miles)
