Misfiring from all 4 cylinders -- Help!!
So I've had a misfiring issue with my car for a while now. The car was throwing a code for an o2 sensor and misfire codes. Here's what I've completed within the last 200 miles: o2 sensor, PCV System Valve, 4 coils, 4 spark plugs. What should I look at next? Any help would be appreciated..
