I cleaned my throttle body sensor today. Actually I cleaned that, replaced my map and maf sensors too on my 05 Cobalt.

I disconnected the battery before any work and didn't have any of the issues those that open that valve have had...it idles better than before and my pickup appears to be stronger also.

My question though is that when I had that valve off the car it doesn't sit straight up and down, it sits at an angle and from what I can tell in videos of throttle body's they appear to be up and down when closed.

Now this thing still closes and there's only a little bit of light that shows through when shut. When I push it to the fully closed position and let go it returns to that slightly angled position.

So am I crazy and or blind?
In none of the videos I've watched did they comment on this being fully up and down OR at an angle making me wonder if mine is flawed and needing replaced.

(My throttle body was dirtier than the worst one in any of the videos....far worse Than the ones the video mechanics said they thought was very dirty. The throttle body cleaner wasn't even removing any of the crud on there by itself...I had to use a rag after spraying it and scrub like a maniac while in the videos the cleaner itself did most of the work.)

Thanks.

If it was shut all the way the car wouldn't idle and it would be hard to start. So it is normal for it to be open slightly. Also you should never spray cleaner into the throttle body but rather on a rag and rub. Spraying in the throttle body removes the lubricant at the pivot point.

Thanks for the reply and lifting my worry over this.

I removed the throttle body from the vehicle and I did spray right from the bottle into the throttle body.
I then used a rag to wipe around. This thing was filthy. Ten years of crud. In a lot of the videos spraying directly onto the crud seemed to dissolve it but on mine it barely made a difference so I used the rag after spraying onto the throttle body which did the trick.

All of the videos I saw on these things did it that way with spraying directly onto the crud.

Should I be concerned with having done it this way?
Anything I can do after the fact to properly lubricate that valve?

Thanks again.

Hopefully you will be okay. The lubricant also serves as a seal against moisture.
