Greetings from bangor. New member here and unfortunately my first post isn't a positive one. Got a flashing CEL in my '03 Wrx wagon on my way to work the other day so I brought it in hoping it was maybe plugs or coils causing the misfire. Turns out the the psi in #4 cylinder is coming up at 50ish. I don't know whats causing it so I am wondering what you guys think on the subject. Is it worth having the engine torn into to find out the issue or should I save myself some time and money and start looking for a reasonably priced used engine? I don't really have the funds for any major project but I would really hate to have to sell the car
