The car had been parked outside overnight, and in the morning it would not run smoothly. The code is for cylinder 2 misfire. The coils and plugs (newish) have been swapped, and the fault remains the same. The plug for cylinder 2 was like new, with little sign of firing. I know humidity can upset this car, but it appears to me that there has been a long term persistent fault (its possibly mice nibbling wires). Can any one tell me what checks can be done please? Thanks, Are PS Do the plugs have torque settings? Thanks again. Are.
