help my w140 m120 92 when start upp revs 4000rpm!??
hello
i have changed the timing chain and adjuster in the engine.
and now when i did the first start upp it was directly going to 4000 rpm.
Second attemp it revved upp to 4000 rpm then whent down to normal idle.
3rd start up it whent directly to 4000 rpm.
and have continued to do so.. can't get it to go on normal idle
the throttle is what i am ussumed to be in normal position. just little open maybe like 5% open. (both sides)
i have checked the vakum lines and they al seems okay.
what i can see it is a smal crack in the smal pipe from the exhoust line to the manifold. but i can't imagine that from a smal crack it will rais the idle to 4000rpm
im really confused. about this problem.
