Thanks for the info, Steve.
Theoretically, it does seem to me like a failing fuel distributor but I am not sure, YET.
Luckily, I still have the EHA harness connected to the EHA with the leads near the driver's console for testing.
I will hook up my ammeter again and look at the lambda set point.
At this point, even if all tests conclusively confirm the replacement of the FD, I am already very contented.
I have got more information in this thread than I could ever dream of and the real reward to me is fully understanding how my car works!
Thank you, Steve, for taking the time to convey the info that you have.
Cap'n - I have had my fingers crossed since this morning; but I seriously doubt that the problem will be solved as easily as that!:pBut who knows...
I'll let you guys know how it goes.
Cheers.
