As part of my troubleshooting with very intermittent severe misfiring and throttle response I'm now left with changing components in the DBW system. This following consistent P2135 fault code (Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation). This translates as fault in either throttle position sensor or throttle body. The latter has been removed and cleaned with no improvement. Current thoughts are that short term fuel trim held in volatile memory of ECU gets trashed causing this issue, currently around every 200 - 300 miles, as a three minute wait with ignition off restores engine to perfectly normal running again.
Chasing part numbers of these two components revealed that Melvin Rutter was able to obtain the throttle pedal sensor under their heritage parts scheme with 25% discount hence just over £100 delivered. The presumably ex 2011-14 Mustang 3.7 V6 part arrived as below with all plastic pedal and perfect Ford number match to OE.

I just need to use hacksaw, drill and Dremel to change it to this, noting that Morgan's steel pedal is bolted at right angles to plastic pedal stub.

Well they do say Morgan's are hand made
