1982 240D throttle linkage sticks
For about 2 months, the foot pedal for the throttle has been sticking. I have removed the foot pedal to verify everything is clear under it. I have inspected the linkages on the engine side. I found a bad plastic bearing at the part that screws into the firewall. Part number 123-300-13-40. Unfortunately, that did not fix it. Has anyone had this problem? It happens when starting from a stop or at up to about 45 mph. It feels like the pedal gets stuck about half way down. Have to release the pedal and push it down again. As you know, the pedal has to be mashed to the floor to get it to go. Any leads appreciated. Do I need to start looking at the linkage under the driver's kick panel?

Definetly check, clean, and lube ALL the linkages and pivot points under the hood. You might also try lubing up the point there the linkages go through the firewall.

You have checked too see that the return spring is in place that is attached to that horizontal bar running along the fire wall?

Recommended lube is ATF.

Yes, that spring is working well. Plenty of pull on it. Table 30 in the little black parts book shows some parts that I need to check out further. I think those are on the cabin side.
