my car seems to run ruff when it goes into closed loop like it has a miss for some reason....it has new plugs wires cap rotor and o2 sensor...... it didnt do it before i replaced all those things, i checked all the wires there all on tight i think it might be the plugs, this has been goin on since around the time i replaced them, but if you guys have any ideas im open to suggestions?

 

you may have got bad o2, it happens all the time. they are kind of delicateand if over tightened the crack on inside too
