I have a 97 Outback (2.5) with 100K miles. Recently the Check Engine (CE) light has been intermittently turning on. The codes that I get from a scanner are cylinder 1 and 2 misfire. The CE light mainly comes on at highway speeds after driving for a while. At times the light will even flash before going to a solid orange. The strange thing is that even when the CE light is flashing there is no noticeable change in the engines performance/operation, the car drives normally! If I drive around town for a day without getting on the highway the CE light turns off. I have replaced the spark plugs, spark plug wires, coil pack, fuel filter and air filter. I have checked the engine timing, compression, fuel injector operation, cam and crank sensors etc. Nothing shows up as a problem but the CE light still comes on. If anyone has any suggestions/ideas I could really use some help before I give up and take the car to the dealership.
