I kept getting a misfire on the first cylinder (P0301) and changed the spark plugs, fuel injectors, checked compression, cleaned air intake sensor... all to no avail. Checked the valve and they were all a bit tight, but especially the first exhaust valve on cylinder 1 (it was at 0.04 and it's recommended to be 0.3-0.4). Guess it's off to the machinist to have them take a look at it. Anyone else been able to get this problem fixed?
