Looks like there was some kind of recall/campaign for the ignition coils causing misfire but mine were probably changed out as there aren't any open recalls for my vehicle or it wasn't included which would figureGot the manual. So far nothing to help out much with the evap code other than it could need a software update which I would probably have to.bring in anyhow. But the misfiring is now the biggest concern as it appears worse now. I had a misfit tissue on cylinder 5 a couple years ago. Replaced the ignition coil and spark plugs and ran seaform through and it cleared up for a.couple of years. Now I am getting random misfired on all the cylinder s. I replaced.the maf sensor based on that when I had disconnected I would get no misfires. The minute I would hook it up misfires.would occur. After replacing the maf it got a little better although it would still misfire at idle.after.cold starter. Then on Friday is misfired out of control while I was driving. One.of.the cylinders misfired over 300 times on the highway and shook all over the place. I let it sit over the weekend and tried it at idle yesterday and again random misfires in all cylinders. Could.it be a head gasket and is it.time to junk it? I doubt all of the ignition coils.would all fail at once? Also there doesn't appear to be any vacuum leaks anymore.
