I have a '94 E320 that has developed an idle that "pulses" from an average
600 rpm up to 750 then down to 500 then it levels out for a while and then starts the cycle again. It doesn't die,it doesn't care if it is hot or cold. It's just the way it is. Are there any ideas where I should start to look to fix? If it matters any, hot starts aren't as good as they could be, I have to press the gas a bit to make it go. Thanks- posted
