My car started running ruff this moring when I stop at a light. The check engine light came on so I checked the plug wires to see if they where loose and pulled the plugs out and they looked fine. Could it be the o2 sensor?

The CEL coming on means the computer has identified a problem within the engine management system -You need to have the computer scanned for the OBD2 code/s Autozone provides this service for free-this is your starting point of finding out what's really going on instead of taking a wild guess on the O2 sensor- might not be it
