Hi. I've been having issues with my car. It has developed a misfire/ erratic idle. I put my cheapie fault reader on it and it showed misfire on cylinder two. I changed the plugs and fitted a new coil pack and it was a lot better but it still has this erratic idle where it sounds as if it's 'hunting'.
I previously replaced the vacuum pipe which commonly fails and I have checked that again but it's fine and to be honest it doesn't sound as if it's drawing air from anywhere.
Could it be the timing ? I've heard that the tensioner can fail and cause the chain to jump a tooth.
All help gratefully received.
