hi i am new to site not sure how it all works. i have a freelander 2002 2.2V6 pertrol. have a problem if anyone can help. my landrover is misfiring thought it may be dirt in the injectors tried cleaner didnt work. started misfiring again on my way to fife so stopped let it sit for a wee while then restarted my journey. started misfiring again so pulled in turned it off and checked my road map to determine my location. switched it back on only to discover my engine management light was on so drove till it was safe to stop and phoned RAC. fault said it was the coil on cylinder A so he swapped the coil with another still had same fault so he switched over some plugs. it seemed fine and i managed to get home have driven it for a few days and it has started misfiring again. anybody any ideas
