Engine Performance problem
2000 Volkswagen Passat 4 cyl Manual 84000 miles

Im getting a misfire in all 4 cylinders. I started with new spark plugs still getting a misfire in all 4 cylinders. Could it be ignition coils. Can all 4 coils go bad at the same time. Make me think its something else.

Could it be a bad fuel filter or crank position sensor could either of those cause a misfire
