Hello!
The light “service engine soon” was coming on and off for awhile until it finally stayed on. Error code P085. When I opened to clean throttle body it actually had 2 blades that covered sort of shafts going down. I cleaned the walls of the shafts and the blades. But underneath the blades if you look down the shafts there is sort of a pane and I couldn’t clean that. Also directly under each of the blades there is a  thin tube-like structures, what do they do, do they have to be cleaned as well? I felt like the engine started to run much better after the cleaning, but the “service engine soon ”light is still on, And the P085 is still current. I tried to look on the website but couldn’t find anything. Also on the pictures(from internet ) that I used to fix my car there was something called MAF screen that had to be removed to access the throttle body, but mine didn’t have MAF way is that?

Thank you so much
