Ok, so in my previous threads I have gone through every aspect of this 240D to stop the shaking madness. Only in gear, only in low idle. Worse when cold, better when warm but still not acceptable. So, the latest thing Im working on has been timing. I found the cam timing to be off by one full tooth. I corrected that last night. Has not effected the idle problem at all. Looks to be about 4 degrees of stretch and no offset key. However, before it was about 27 degrees due to the tooth so I was hoping for some gains when corrected. Nope.

Here is the reason for this thread. The injection timing, determined by the wellling up method is about 7 degrees BTDC. Way retarded for an 81 240D. Should be 24 +/-1. The pump is pulled away from the engine the full swing of the bolt slots to achieve this. So, tonight I push the pump in toward the motor to advance the timing to about 25 degrees BTDC. Not perfect but a lot closer than 7. Car will barely start cold. Once running sounds like its knocking a bit. Tons of black smoke. Stalls in gear in low idle. Much less power. Terrible shake! So I swing the pump back to full retard and its back to better idle and driveable. But still not right. Could someone please explain to me what could cause this??? HELP!!
