hi guys . can anyone help here please.
over the last week or so my car has started to what seems like ' miss firing' when I'm at the lower range band (around 800-1200 rpm) and then it will do it when ive changed to 2/3/4 all at low revs , but as soon as i start to put my foot down and reach 3k it seems to disappear ( until i change ) i have changed my coil rack last year so surly it couldn't be that ? any ideas . possibly just change the plugs ?
