They fixed another issue, but the misfire (the reason I brought the car in) is still happening. When the problem re-surfaced, I brought the car to my regular mechanics who read the codes to find the same two misfire codes present. I can send you a copy of the invoice if you like (but some of it is in French) Sasha

Unfortunately it's not shown a pattern I can recognize. It's most likely to occur on the highway, but has shown its self at city street seeds as well. While in the highway, it can show when acceleration, decelerating or running steady with cruise control. When it does happen, it can be several misfires in a short period of time, a isolated incident or nothing for well over an hour of travel

It's an intermittent problem. The most common time for it to occur is when on the highway. It's just as likely to happen when accelerating, as when decelerating or running steady on cruise control. In a 3h drive it'll generally happen 4-6 times, but the timing between seeing the check engine light flash seems random. It can happen anywhere from a few times an hour to not at all for well over an hour. When it does misfire (once or a few times), it can happen anywhere in the beginning, middle or end of the drive.

Thanx for your reply The coil was replaced by the dealer

The dealership replaced the ignition coil, spark plugs and spark plug wires as part of their 'fix'. The plugs and related wires I though were a little suspicious as they were replaced about a year ago by my regular mechanic with NGK products. But the dealership claimed that as they weren't the manufacturer original parts they were causing issues.

Hello I have a feeling the dealership is taking me for a ride I'm not a mechanic and am lacking knowledge and technical terms, but I believe the problem is well described below. My 1995 Legacy LS wagon (253,000 km) began inconsistently misfiring a few months back. At first it was only on the highway so I didn't feel the car jerk but did see the check engine light flash. My mechanic couldn't pinpoint he cause so had me continue to drive, asking me to bring her back if the problem got any worse. Over a few months, she began to misfire somewhat more consistently and now at city street speeds (at this speed I could feel the car jerk), so I brought her back to my mechanic who still couldn't pinpoint the cause and so sent me to the dealership. After a 1600$ repair bill where they worked on this and an issue I had where she was sluggish for 5-10 min of driving from a cold start, the dealership informed me that the Crank Pulley is bent, dowel pin for crank is worn and crankshaft is getting worn due to the dowel pin. While the sluggish behaviour from a cold start seems resolved, she's still misfiring. At this point it's back to being less consistent, most of the time at highway speeds but occasionally at street speeds. I brought her back to the dealership and they promptly told me that it's because of the bent crank. They went on to say that this was a diagnosis they could only make once they were working on car and disassembled the components to some level. With the engine running I can see a slight wobble in the lower wheel that the timing belt passes around (sorry for the non technical terms). The misfire codes Subaru recorded were P0304 & P0303. same error codes persist after the work they performed. Is the bent crank somethign that should have advised me to before any work was done or are they now trying to cover their asses from an oversight on their part?
