I have the same idle problem with my 190e 2.5-16v. When it's cold it runs fine about 900 rpm but when it warms up it idle start to flactuate. It goes to 1400 - 1500 rpm, some time it will go back to 900 rpm for a couple of seconds and then it's back to 1500 rpm. I've checked the OVP relay fuses and they are allright. Somebody suggested that the automatic choke may be cutting in, how can I check this ? Can I disconect it ?
