I have a 2000 Ford Fiesta 1.2 Zetec (Zetec engine & trim, not just trim name!) with a misfire on no. 3 cylinder. I have been told this is likely to be a burnt exhaust valve - both the injector and spark plugs are fine, and no other cylinders misfire.
I intend to fix/replace the engine, although the car will be stood up for a few weeks (maybe a month or two) before work can start on it (due to funding). I intend to tick the car over periodically as normal, as though there wasn't a misfire - maybe once or twice a week - just to keep the electrics going.
I was just wondering if there are any inherent issues (other than damaging the catalytic converter) with starting and ticking over a car with a misfire on 1 cylinder? She still fires up and runs, though only really for loading purposes. I don't intend to move the car, just keep the electrics going until I can transport the car.
