Throttle body cleaning

[johnptfisher]

What if any improvements have you noticed after cleaning the throttle body. I just cleaned mine as it was pretty bad. It now looks brand new. I did notice a tiny bit better performance and smoother idling.

not much unless it was really fouled out.

you might have to make it a reg thing now. I do mine at each oil change don't take much to do and youd be surprised how dirty it gets and fast.

It was very easy to do. Took me just under an hour start to finish. I kinda wonder what GM was thinking with the whole air intake system. This is my first Chevrolet and have never seen and intake such as this one.

I usually clean my TB every other oil change to keep the build up down and idle smooth.

I took the throttle body off and cleaned if thoroughly.

I just recently did mine and it made a little improvement, not as much as others have stated in many posts. So, I had it tested and it failed so I wound up having to replace it. The new one made a huge improvement. I also just replaced my CPAS and the two changes made a dramatic improvement in the rough idling and improved gas mileage about 2-3 mpg.

Have you ever owned a VW? These TB's stay pretty clean.

I've never noticed a difference when the cleaning was not done due to a dead or disconnected battery.
