Hi all

I am cleaning my TB as described in the topics above but as i am loosening the iaa screw it doesn't comes out, i've been trying several ways but no result... any solution? is it usual?

I had the same problem when I cleaned mine a few years ago. I couldn't get that screw out. I tried a few different methods, and then gave up out of fear of stripping or damaging the threads.

It always bugged me that I couldn't get that area clean. And I sometimes wondered if it had anything to do with an idle that at times wouldn't drop to where it should be.

I have the same feeling, because i havent had any improvement with the idle after all the morning cleaning all the tb and adjusting TPS, now im thinking about distribuitor...
