Hi, I have been trying to sort out why my 240D "ran away" on me this morning. To explain, I was backing out of the driveway, lightly pressing the accelerator. I let off the accelerator and pressed in the clutch pedal because I was breaking as I was about to exit the driveway, and when I did this, the RPMs took off. I was unable to get it to stop by letting off the accelerator or by turning the key off. I had to let out the clutch against the breaks. I started up again, and it took off again.

I rolled it back down the driveway, not wanting to have that happen again. When I was back in my parking space, I popped the hood and started it again, and it was idling nicely like normal.

I tend to think it was something to do with the throttle linkages, but I am not sure.

When I press the go pedal, it seems that the linkages come back fine, pulled back by the spring near the firewall back by the oil filter. But when I move them by hand on top of the valve cover, they move to open but don't go back until I push them back.

See this video, it shows this linkage action:

Someone also mentioned to me that there is supposed to be a spring for the linkages by the IP. I look, and I don't see any spring there. I have attached a couple pictures of that area. Could you tell me if you can tell if anything is missing? If I need to take a picture from a different angle, let me know.

Look between the injection pump and the oil filter housing, I can see the broken spring hanging down there in the picture.

Thanks again. Should that spring attach to the flat lever type end of the series of linkages that hits against the IP at WOT? (see picture)

Yes, if you want to reuse the spring, simply bend out one of the top coils to be a hook, then hook that to the "lever type thing" it should hook right into a small eyelet.

pearl black 1983 240d 4speed (Converted!@$$%) atleast the tranny was rebuilt.

Yep, thats exactly it.

Just go to the hardware store and get a new spring. Bending springs is a pain in the a@#
