Thanks chaps. One of my first stamps was to spray contact cleaner on the MAF and Stepper connections. I haven’t cleaned the ECU plug yet as I’m waiting for the resistor to arrive so I can solider it into the loom before reconnecting the ecu. Don’t really want to disturb this big plug more than is necessary.

No harm in cleaning the MAF contacts again though.

It has the signs of a duff connection somewhere as it’s inconsistent.
