Rough idle? Not anymore! (throttle body before and after)
My 2013 5.0L had been idling rough for a while. I am a little over 98K miles so I replaced the spark plugs and gapped them to .045. Still rough idle, especially in gear at stop lights. It even went dead a few times. I tried several tank additives (Seafoam, BG 44K, etc) and nothing helped. Next was the MAF so I cleaned that. Finally, I took the throttle body off yesterday it had MAJOR build up. Cleaned it with throttle body cleaner and an old toothbrush, reflashed my tune, ran a can of Seafoam upper engine cleaner through the throttle body while running the engine, and the truck literally sounds and feels brand new. It was probably a combination of the upper engine cleaner and throttle body being clean, but man that throttle body was BAD.
I did not expect it to look that bad!
Clean as a whistle now.

Looks good, nice info.
Did you put your wife's toothbrush back where it belongs in the bathroom.

In my line of work I've seen them a lot worse than that but yeah I agree, the combo of upper intake cleaning along with the T body makes a huge difference.

To be perfectly honest, I'm not certain how it would be applied on an eco, I left the dealer back in 04.

You would inject the chems directly into the intake bypassing turbos or disable the fuel system and connect the chems to the fuel rail. We used BG at my dealer, came with a tool to do just so, no turbo's on the gas engines but we have done a few powerstroke diesels.

i have read where you have to be careful with eco's as far as seafoam type treatments go.
Thanks for your honesty!
I have some time still as I'm only sitting at 19k miles after 5 years but you always have such great insight so thought I would ask.
