#1 of 3 2004 Forester: P0301 - P0304, P1447

2004 Forester getting check engine line codes P0301-P0304 and also P1447 every 2 weeks. Car has ~105000 miles.The first four are cylinder misfires; last one is some emmision code. Anyone know what it is and what this can be due to? I have the same problem at 60K (except for P1447) and now it's back.

Just curious, what work did you have done at 60,000 after the first event?
With all four cylinders recording misfires, I have to think it is a fuel or spark issue. If your plugs and/or wires are old, that may be a first place to start. If the car is not running well, it is likely that emissions codes could follow, so I would start with addressing the engine health and see if that clears up the other issue(s).

* fuel filter
* fuel pump
* ignition wires
* spark plugs
* ignition coil
If all 4 misfire it can't be a fluke.
