I have just rolled over 3200miles in my WRX. I got a CEL codes. Got out my code reader and got 4 codes. Cylinder 1-4 all giving misfire codes. I havn't run the car hard really, its had it oil change, and it happened on a dry day in the upper 50 degree range. Any thoughts are advice on this? The Dealer here has only one Subaru tech. ( Yeah one tech in the whole city) So I can't get it in for a while. What could I possibly do to fix this? I know the plugs are going to have to be checked, anything else I should check, or anything to look for? Thanks a lot.
