My '86 300e has a low idle. The engine shakes in gear at a light, otherwise the car runs strong.

I see Bentley's E-class Owner's Bible says to remove and ground the violet wire from connector 26/3 to increase idle by 50 rpms.

Where is connector 26/3 located?

Thanks in advance.

Have you checked spark, idle control valve???

Thanks, Cartagena.

I've solved my low idle problem by adjusting the EHA (electronic-hydraulic actuator) that is attached to the fuel distributor. There's a tiny hex nut under the screw on the EHA. The car starts and idles fine now after turning the nut a quarter turn to the right.
