1998 Subaru Legacy 4 cyl All Wheel Drive Manual
Hi, i have a 1998 subaru legacy wagon with 175k. Yesterday while passing a car the check engine light came on and it started running rough and now ticks. I had auto zone check it with their machine, it said misfire in all 4 cylinders. They recomended new plugs and wires, i did that and it runs better but still rough. I checked firing by removing wires with engine at idle and #2 seems to be where the problem is, no change with or without wire. What now? And what else should i replace at 175k?
Engine running rough or misfiring can be cause by the following:
1.Defective spark plug
2.Inadequate spark/coil,defective spark plug wire.
3.Lack of compression
4.False air leakage.
5.Faulty fuel injectors.
6.Insufficient fuel pressure.
8.EGR valve that is leaking.
10.Throttle position sensor.
11.Idle air control valve.
