Our 1997 Outback, 2.5L twincam, has started throwing up "check engine" lights with the error codes just saying it has detected misfiring in cylinders 2 and 4. No further clues as to cause of misfire. When it is driven there are occasions when indeed it seems to be weak, but if I really push it it responds and after I "blow out the gunk" it will work nicely for a while. If I clear the codes they stay off for a while, I think it is not supposed to repost them until it has been driven something like 50 miles with repeated faults, but eventually they come back. I have looked for any obvious loose hoses, wires, etc., on the left (driver's view) side, where those cylinders live, as well as searching around for other possible causes. Before I really take everything apart, are there any causes that seem to come up frequently with these symptoms? (It had new timing belts, pumps, seals, etc., not too long back. It had a compression leak in the head gasket that got fixed, on the other side of the engine. I cannot find any connection between work done and the present symptoms.) Thanks! Bob Wilson
