I have a 2006 Ford Focus, which seems to have a sticking throttle body problem.
When I checked the Chilton manual, it says cleaning is not recommended for 2005 and newer Ford Focus, because the inside of the throttle body is laminated with something, which could be harmed by cleaning solvents.
Does this make sense?
Why do you think this is? Should I clean it anyway and see what happens?
My car sometimes idles as high as 3000 rpm for a few minutes. It started doing it as the weather got cold. It then gets back to normal, idling at about 900.
Check engine light has not come on.
I am thinking of cleaning the throttle body first, because it is the cheapest and easiest solution.
