Chip,
Remember that a 240D is SIMPLE. There is nothing hidden or complex.
You should be able to see EVERYTHING from the bushing through the firewall to the last bit of linkage just looking into the engine compartment.
(ONE possible exception - there may be some mechanical linkage down to the transmission in a car as early as yours. IF SO, disconnect that linkage at the top ball end and see if that eliminates your sticking problem. If it does, you have isolated the problem.)
Does the problem exist when the engine is OFF?
Without adjusting the rods, you can disconnect the sections at each ball. Start with the section nearest the firewall. Disconnect, then see if the problem remains. This way, you isolate the area in which the problem occurs. You may find a ball that is still binding, despite your lubrication effort.
Have you crawled into the footwell, on your back, being in pain and discomfort and positions that the human body was never meant to assume, and checked to make sure that while sitting for 6 months there was no squirrel's nest (or hornet's nest), or bunched up carpet built up that is blocking the pedal movement?
Because the 240D is such a simple, straightforward design, the solution to your problem is going to turn out to be simple, once you find it.

I will guess that, from half-way and on, one of the rods that is bring pushed is bowing. Something is keeping it from moving further, and it is bending sideways. Can someone watch the whole linkage while you are pushing on the gas pedal?

So I lubed all the balls. But the problem persists. I believe it might be the it may be the bushing in the firewall. How do I access it from the inside of the car I can not even get my fingers up where it travels through the firewall. Is this something I accessed from underneath the car?
Even after lubricating all the connections the pedal feel is linear only halfway through its travel and I really have to squash down hard that second-half where it only moves a fraction farther. I'm guessing it has to be the Bushing but I'm not sure how to get to it.
