Clean out intake use sea foam directions on can. This is the cheapest fix but usually does the trick.Put in gas tank as well as crank case.

1988 Mercedes Benz 300E 3.0L Gasoline F.I. ''Sputtering at Idle


ok..you must have more than one car???? you don't drive the 300 atall im guessing. #1 start car drive up the road and \back to your house. #2 let it idle till problem starts. #3 once it does start with the problem keep it alive with the gas pedal. #4 once your have it safely from dying in higher rpms "rev it" like a kid would, you know like if you were gonna race some one lol. be careful not to over rev or damage engine. you should do this for five minutes no longer than that. #5 let it idle for another 5 minutes. #6 repeat every day until problem with idling decipates. it took mine 3 300e like 3 days of this. if your not going to drive the car once you get the problem out of the way. turn the car on everyday and let it idle for 5 minutes atleast and take it for a short drive once a week. they get lonelly you know lol. later on you can just turn the car on every 2 -3 days and let it idle but still take it on a short drive atleast once a week

it sounds to me that you idle controll valve isnt responding (could be dirty) get a can of carb cleaner and clean the thottle body inside and with the engine running. squirt just a little and the engine will start to stall and the idle air controll will start to open ( you will hear it start sucking) then spray more in sperts try to keep the engine running at idle . this will make the engine RPM's change and open and close the idle controll valve thus cleaning it. when done save some carb spray. put the air cleaner hose back on. and start the engine and with the engine idling spray around the intake and base of throttle body if the rpms change you have a vaccume leak than will need to be repaired.
good luck
