Sidom Veteran / Moderator Aug 2, 2009, 9:39 AM Post #2 of 3 (4367 views) Re: 2003 pontiac sunfire misfiring Sign In This system uses a type of waste spark system basically 1 coil fires 2 cylinders..... the pairs are 1&4, 2&3. So if the codes you got were P0301 & P0304 or P0302 & P0303 that would indicate one of the coils isn't firing. unfortunately you can't swap coils on this one to see if the problem moves... Considering what happened I would probably be looking a connectors for signs of water, maybe taking some apart to see if there is any water in any of them.......... I suppose its possible for one side to go out but it sure seems coincidental considering what happened....... By the way.... What codes did you get?
