    Hi all I had a misfire about a month ago got the rac and they said it was cylinder 3 changed coil 1,3,5 and was fine till last week came up cylinder 4 and 6 so fitted a new one for 2,4,6 yesterday also changed all the plugs while it was apart, driving round was fine and sounded sweet, eml went off after a few starts aswel, soo... Driving home from work last night I put my foot down a bit not far from home and a misfire happened again with eml light flashing... Pulled up at home sat there for abit with engine running and sounding abit rough, revved abit and it cleared/light went out, what could this be? As I need my car every day for work just need to get sorted doing my head in abit now after replacing both coils and plugs... It's a 2003 3.2 v6 any help I would be grateful !!
