Hello,

I have a 1993 300SL (W129, 104 engine), when started from cold the car idles at around 1100rpm. After driving and warming up, when the gear selector is returned from D to N or P the idle RPM goes to 1500 - 2000 and stays there even after briefly depressing the accelerator. Any ideas as to what might be going wrong will be greatly appreciated. I have checked the throttle linkages and at idle they seem to be in the correct position. Many thanks in advance

Valtcho
