Hi, it's the 2.0 litre petrol. I have changed the plugs and coil packs already. The erratic idle goes up and down quite dramtically. This issue came out of the blue . Initially the error codes appeared to be random (see first post). When I Googled them,one was related to an oxygen sensor, one was related to signal from the alternator , one was the throttle potentiometer and one was the throttle actuator. I'm completely baffled.
Thanks
Dave
