i have an MG zs 1.8 16v injection. i start it in the morning and it would not idle the pin was up and down, and sounded like it was misfiring,also the orange lengine light came on. i started it this afternoon and it ran like a dream. the problem started 2 weeks ago,its been ok when it is warmed up but misfired once or twice on a 10 mile journey. i have changed the plugs.checked the air filter, and lubed as many connectors i can find. starts when cold but isnt idling properly. any help appreciated.
