Question

Hi, My 1999 Ford Fiesta 1.25 Zetec has developed a misfire over the last few months. It is worst when the engine is at normal operating temperature and i lose power when accelerating particulary at low speeds. The car is very jumpy when accelerating. It is fine cruising on the motorway. I have had the spark plugs and leads changed and this fixed the problem but not completely. It is now again getting worse and occasionally the car will stall. Any ideas? Thanks


Answer

check the plugs and leads, a special grease should be used when refitting plug leads otherwise you can damage them
