Ok I know it says not to clean our throtle bodys but I'm thinking about trying. I bought my truck in july 2009 with 138000 miles on it and it now has 152. I can't seem to get it running as good and smooth as I would like and I plan to check the throtle body next. And I have tomorow off so I plan on takin in air box off and inspecting it. If its dirty I was thinkin about takin carb cleaner and a tooth brush and cleaning it. Has anybody cleaned theirs before and how did it turn out? Its a 2004 5.4

 

If you do it, use tb cleaner. It's supposed to be safe for the finish.

 

Ok ill pick some up in the morning. I'm not gona touch it if it looks ok but I'm running out of ideas so I'm gona check it out.

 

Only use non metal things to clean it. An old toothbrush and carb cleaner to get the gunk off then a shop towel to wipe it clean.

 

Ford throttle bodies (at least on a '93) have a warning label to not clean the throttle body because you can remove the teflon coating and the plates (butterflies) will not seal properly. Use TB cleaner and a rag on your finger.

 

just cleaned up 20 years of blildup from this 4.9 f150 used a small wire brush and oven cleaner .. all back together .solved the idol problem and runs much better

 

DO NOT TO USE ANYTHING BUT THROTTLE BODY CLEANER.

On these newer Fords, there is a coating on the inside of the throttle body. Carb cleaners, oven cleaners, and others can remove this finish.
