So I start the car up this morning, and wouldn't you know it, runs perfectly. Checked the duty cycle out of curiosity and its perfect.
Drive the car around during the afternoon. While on the road home, notice it wont accelerate and is hesitating in the higher RPM ranges (remember- 300SE will cruise at 3500- 3.46 rear end!).
I get home and once again, she is reading 10% (sometimes fixed) at pin 3. Starting her back up is a chore and she doesnt want to idle with out a little gas pedal persuassion.
Mail came, and with it, my test harness. Just got her plugged in and will report back with the results. By the way, your (Martin) pictures of the set up (from a previous thread regarding your 560) have been worth a thousand posts.
So problem only occurs after car has been driven for a bit. Hmmm. Ignition coil?...I'll get to the bottom of this.

EDIT- Oh yes, she sure is sucking down that premiuim petrol!
