Throttle body stop screw - Adjustable?
My focus 1.6 petrol sticks on the lowest gas pedal position. I know its the butterfly sticking. Throttle stop screw is worn a little. So i put 3 layers of electrical tape together and laid it between the stop screw and the stop plate. And that was enough to fix the problem. But this tape will get worn so i have to fix it more permanently.

Does anybody know if the stop screw can be turned? When i feel the backside of the screw i fell that the screw has a round head without the possibility to put a screwdriver into it.

Use metal tape. Like (real) duct tape. It is aluminum metal with a sticky backing.
It will last much longer.
I had used it on my Contour SVT throttle stop for the same reason.

Thank you!

I will try that, i know i have this aluminium tape somewhere in my home. I got it with a dishwasher mashine to tape above the front opening to avoid moisture to the kitchen table. The tape was the same width as ducted tape.

So in this answer from you i assume you found out that you could not adjust the trottle screw?

The US model is adjustable with an allen wrench. It's hard to see it, but it's an allen head screw.

No i cant see it but i feel it is round like a half lemmon, maybe the hole for allen wrench is filled with epoxy because it should not be tampered with.

Loosen the 2 screws holding the throttle plate in place. Force the throttle open then closed, push it closed a little while tightening the screws.
Should help.

The first time I looked at mine, I used a mirror to see it. As I mentioned above, that's US model. I don't see why yours would not be the same.

I drilled/knocked out the epoxy on one I was trying to fix, and there was an allen screw inside. I used my Scangauge to set the idle TPS percentage to factory specs. I would try what 'iminhell' suggested first it works too, especially if you don't have any way to look at the TPS readings.
