finally this morning my car went to cut out like it has many times but actually kept going, pulled over plugged it in to my machine, noticed the eml light was staying on and very bumpy tick over, it read four codes P0301,0302,0303,0304. uuuuuuuuuuuuuummmmmmmmmmm wonder what that could be! :-) so i checked sure enough the book says misfire 1,2,3 and 4. which would explain the bumpy tickover.i then thought better take it home, so turned around and thirty seconds up the road the bumpyness went, eml stayed on and car drove perfect! got home, it cut out checked it on machine again. no codes showing! can this be related to a coil pack?plugs or something?anyone any ideas? sorry about the long post!
