hi.
i have a 92 190e 2.3.
new problem started last week out of the blue. first thing when cold and only when cold the idle will hunt badly, it goes to about 1200 rpms down to almost dieing and back up and back down over and over untill after a few mins and once its warmed up it idles fine (not perfect but ok). after that it runs normal upon restarting. i cleaned icv, checked ovp fuse (no lights are on), cleaned throttle postion switch. been looking at past threads alot lately and cant quite figure that problem out. any guesses what i should try? thanks batman
