well my engines bogging and idling funny again i was wondering if it could be an 02 sensor by the cat . I replaced my plugs cap rotor wires and the points . A while back my cat got clogged and messed up my fuel injection and we fixed it after that it was running alright but the bog came back today.

is there an 02 sensor by the cat?

 

Just in front of the cat is one on mine , and mine is a 94

 

thanks
