Okay, on Motronic engines, if the basic timing, as in distributor position, is correct, the advance/retard function is handled by the ECU. To check the basic mechanical timing, you have to remove the threaded plug in the top of the bell housing, which has a plastic cap covering it. It requires a special tool, which is basically a giant Allen wrench that requires a 3/8" drive extension and ratchet to remove. There are notches in the flywheel, and a pointer cast into the bell housing. As I recall, you have to plug a vacuum line, and then shoot a timing light down the hole. Again, if I recall correctly, there is one slightly wider notch in the flywheel, which when aligned with the pointer, indicates TDC, or 180 degrees out without the engine running. Then there is a slightly narrower notch, which indicates correct timing when lined up with the pointer, and the engine idling. If it doesn't line up exactly, you rotate the distributor until it does. The whole procedure is explained in the Bentley manual. It's been a long time since I've done all this, so double check the Bentley to be sure my memory is correct. One other thing, you asked about fuel injectors. I researched larger injectors when I was building my car, and with Motronic injection, there were no options other than sending the stock ones out for balancing and blueprinting, so unless you have one or more faulty injectors, that is not likely part of the problem.
