EZL Timing Question
 

My 86 560sl has EZL igntion/timing I believe. If I understand this correctly, there is a sensor somewhere that reads and automatically adjusts for proper ignition timing.

As part of a water pump replacement I had the distributor loose (not completely out but I pulled it up about 2" to get at the adjusting bolt.) It slipped right back down.

When I took it loose, the adjusting bolt was pretty much centered in the adjusting slot so when I put it back, I just centered it as a starting point. When I got all buttoned up, it ran like crap. I adjusted the timing and tried both extremes, all the way counter and all the way clockwise. It won't start at all in the all the way clockwise position, starts and runs fine albeit with poor idle at the all the way counterclockwise setting. When I put a timing light on it, it reads 15degress at idle.

My question is, if I got it a tooth off when I put it back in, would this account for my stumble at idle?

Any help will be appreciated.

Thanks.

Best way is to bring the # 1 cylinder up to TDC and then look at the distributor rotor, to see if it is pointing to # 1 terminal in the cap.
If your out by 180 degrees, you probably don't have the piston on compression stroke, so come around once more.
The fact that the engine runs ( although poorly ), would suggest that your timing could be off by one tooth, and you can't get it set, because you have limited movement on the distributor adjustment.
Try it, won't take long.;)

Where is the EZL Plug?
 

Sorry don't know that one.

How about another clue?
 

Near the ?
On top of the?
Beside the ?
