I had the AC recharged in my '86 245 yesterday (R12, don't ask the cost!) When I drove the car home, I had an awful time getting moving. The car would buck and had little power. After I finally got up to speed, it ran OK and it idled well. AHA! says I, after my education on the Brickboard, the AC mechanic may have knocked an air /vacuum line off or---doom and gloom--- my AMM bit the dust and I'm in the limp home mode.

That evening I looked for a loose hose and found none. So much for the easy answer. Today I was following the Bentley manual's suggestions for drivability checks and started to clean the throttle body. While pulling the accordion type air hose off of the throttle body, I discovered that it was not clamped to the AMM. I guess that the AC mechanic had pressed against it while connecting lines to the AC and it slipped off. Reconnecting it solved the problem.

Now here is the odd thing. The air hose had enough "stiffness" to press itself tight to the AMM when the engine was stationary thus the engine ran fairly well at idle and steady cruising speed. When I let out the clutch on starting, the engine torqued over to the right, the hose moved away from the AMM and the engine essentially dropped into the limp home mode. At least that's my theory for now. What do you think?

Sorry to make this so long but when I removed the throttle switch, it was full of oil. The throttle body was not oily. What gives?
