Joe W Posted December 1, 2008 Share Posted December 1, 2008 Over the past 2 weeks my car has started acting up. What its doing is it will bog under accel or if I open the throttle past a quarter, after driving it like in "bog mode" for extended time (engine is constantly bogging) the cel will come on (ecu diag code 1 i think- oxygen content). Also does it if revving without load. Honestly it sounds similar to a wrx w exhaust; I did add an aftermarket exhaust like 2 months ago if that helps at all. Seems like the O2 sensor may be fouling, but not 100% any thoughts. Link to comment Share on other sites More sharing options...
Joe W Posted December 2, 2008 Author Share Posted December 2, 2008 Not a bad O2 sensor. Bad spark plug wires are the culprit, they were arking some kinda bad. Gray wires were blue soo just replace those prob fixed. Link to comment Share on other sites More sharing options...
