1989 560 SEC
idle problems
I have an '89 560SEC-let me preface this by saying that I have been playing with the idle mixture -when I richen it -it starts fine- 1100rpm down to 750-but as the temp gauge goes up so does the idle so I lean it a bit just to make it bearable-but then the cold starts take a while -the idle control valve is good-unplug it and the idle races-had the ICU checked and thats good too-complete tune up-new injectors,coolant temp sensor(2pole)fuel pump relay-any help is greatley appreciated!
