Question about 1998 Subaru Legacy
Have DTC Code PO101, a miss fire in cylinder #1. I have inspected the spark plugs but all are in good condition. A tune up was done approx. 30k miles ago. The fuel filter was slightly restricted but just barely. The wires ohmed out within spec's. Originally, had a PO103 code along with a PO325 knock sensor code. Resistance was out out range and replaced the sensor. The resistance on the coil reads good but I haven't seen it on the scope. I don't have a scope to see and read the ignition patterns. The resistance at the injector is good, 11.5 ohms.
problems occurs after the car warms up and intermittently. what am I missing?
