I’ve had another idea of things to test. So the camshaft position sensor (CPS) tells the ECU when to fire the sparks. Maybe this information is not getting to the ECU when the engine gets hot. i.e. the wire that connects the CPS to the ECU is shorting? But then I’ve looked into this and according to post 3 of this thread the “ECU reverts to batch injections” when not receiving a signal. So should still run without it. https://www.mg-rover.org/threads/camshaft-position-sensor-problem.484531/

Then I thought maybe the crankshaft position sensor is faulty. Anyone know the location on a car like mine?

I’ve read that I’m looking for about 800ohm across the sensor. Could it be shorting once it reaches a certain temperature?

Note I’m not getting rough idling, misfires or hard starts so its not showing the usual signs of a temperamental/faulty crankshaft position sensor. I’m thinking maybe its either working, when engine cold, and shorting when engine hot. What do you think?
