Cleaned my throttle body and picked up 3mpg....
Truck: 2014 f150 limited ecoboost 4wd with ~76,000 miles.
I cleaned my throttle body recently, which didn't look that bad, and reset the KAM. Doing those two things only I picked up 3 mpg. Was averaging via hand calculated 13.3 mpg and now I am up to 16.4 mpg over the course of three tanks of gas. I can't believe there is that much of a difference but after three tanks it hasn't changed.
This is all due to the throttle body being clean. I have reset the KAM three times now, once when I first bought the truck and replaced plugs and boots and once when I cleaned the MAF sensors about a month ago. Driving habits haven't changed and up until now I was only able to get max of 13.8 mpg.
Has anyone else seen this much of a change?

56k on it, and haven't cleaned the TB yet. But you're making me want to run out there right now and do it!

I saw a full MPG after cleaning MAF, T/B and cleaning and re-oiling my S&B air filter that came with my JLT CAI. Did this about 8k miles ago (re-cleaned and oiled filter since) I've steadily maintained that gain. Now that was probably in April so part of me wonders if it was also winter fuel running through...

I have a 6.2 and slowly began losing mpg's around 70K. Thought it was fuel but no matter what I ran, same results.
Cleaned the MAF, got it all back. All back to normal now at 13.8 mpg.

A ratchet and I believe an 8mm or 10mm socket. Something to remove a hose clamp. It is 4 bolts on the TB. Takes like 5 minutes to remove as long as you don't drop that socket and then spend another 2 hours looking for it because you are worried it dropped down into your CAC.
