2020 Outback Touring XT and 05 Outback 3.0R
I have an 05 Outback 3.0R and my check engine is on. I scanned it and it showing me that misfiring detected cylinder 3 & 4. The current mileage is at 108k and the spark plugs are original. The mechanic told me I need to replace the spark plugs and the ignition coils. Is there a way to test if the coils are bad? I've read somewhere that these coils are bullet proof. Also, what are the locations of cylinder 3 & 4?
