a friend of mine jacked up his head. it's a 95 accord ex f22b1. he replaced the head, timed it, and test drove it. it jumped time. we fixed the timing, and got it "running." it runs rough, rich, and throws a cel. did the jumper trick, got 3 short blinks and 2 long blinks. looked around, and can't find what this means. we are desperate for help. Anyone?
