Shaking Motor All the Time 1985 735i

As you start the car it has a rough idle. as you give it gas it stays the same. I think it may be fuel injection. Every now and then it shuts off on it's own. I put in fuel injector cleaner but this did not work. It just started one day out of the blue, before everything was good. Thanks for your ideas. JorgeS

I would suspect the idle control valve (bad or dirty or electrcial lead is loose). If you can locate this item (near the throttle body and long, black plastic/metal tube with hoses and electrical leads attached) I would remove it and clean the interior port with a throttle body spray cleaner.

Mea Culpa. it is realoem.com. You enter, go to archive and E23, the browse parts for fuel preparation and you will find a good schematic of the part I refer to.
