Stomp Test Code 1213

Which O2 sensor is this one, code 1213, left or right side?

heh... probably an intake leak, very common as the weather gets colder. Reboot the computer and youll probably get another code, all coming from a leak.

Thanks.
I cleared the codes several days ago and got the same code the next morning. It is getting colder here, around the mid to low 30's. I recently had the water pump replaced, and later the thermostat housing replaced. I will check the setting again and the intake connections and fittings.

most likely the intake gaskets and plate gaskets, did mine big improvement but forgot to do the front plate...someday i'll pull it back off and do it all right.
