DIY Throttle Body Cleaning
Posted on this subject back a few years ago and wish I had stepped up and made it happen back when. 130 k miles on the ride as of now and decided to climb inside and remove the TB for cleaning . Parts bought,,new Wix airfilter, 1 throttle body gasket
Can of TB cleaner and one more of WD-40. There are three hoses I recommend spraying about a hour before going in for the removal of the TB. 2 hoses at the TB that carry coolant and one hose where it goes into the air intake boot,
The link below guided me in, though the intake boot on my ride was not like the one in the link, but close enough for me to remove and fix the problem I had with a TB that was going to cause a bigger problem , if I hadn't acted.

That gent says dont spray cleaner on the TB
I sprayed it heavy and cleaned both sides of the butter fly to where there was no trace of carbon,,he didn't . Q tips will help and using a screw driver handle to keep the butter fly open when cleaning helps also. This is a drive by wire TB not by cable.
I also use Deoxite on all the electrical connectors and cleaned the MAF as well with TB Cleaner.
Finished it late last night and then drove today and couldn't tell the engine was even running while sitting at a traffic light,,throttle response vastly improved. Don't try this if your not into DIY stuff. I have been cleaning these types of TB's
for years in all my cars and wished I had done this before now. I'm going to start cleaning the TB every 50 k miles,, the carbon on mine was so thick it looked like paint, Was a wonder the ride ran as great as it did,,now it's much better
Hope that helps

The link below is the one to watch for removal of the TB , the one above shows a bit of cleaning, though I don't like the out come of what was accomplished. The TB needs to look shiny with no trace of carbon build up anywhere.

Forgot to add , when opening the butterfly on the TB, do it slowly with even pressure , don't just grab it and wrench it open, do it slowly , there are electrical components that could be harmed by opening the BF to quickly. Opening it quickly can generate
small amount of electricity and that could cause a problem..
