I have noticed your responses and hope you can help me. I have a 01 S40t 1.9l. My oxygen sensors were bad, I knew they were and before I could change them my car suddenly wouldnt start. It turns over but won't start. OBD reading was something like cylinders 2 & 3 weren't hitting. I replaced oxygen sensors, spark plugs, and it still won't start. I had cleared the codes and now there's no reading. What would you suggest? This car has allot of miles, 140k or so.. Any help would be greatly appreciated..
