Try to get the code,
2nd O2 may be going out. Are there any drivability problems when the check engine light appears?

This code indicates slow response on second O2, one in that massive L shaped O2 restrictor. While the sensor might be getting older and not quite as responsive as it used to be, it could very well be too far removed/restricted from the exhaust flow so it doesn't "see" enough of the exhaust gas. I've had good luck in using Vibrant restrictor with adjustable inserts, and find that middle one works very nice wherever I put it, no issues even with older sensors on some older cars.yeah I would love to know how to resolve this.
CEL? I think they are referring to O2 sensor. This is where Vibrant restrictor is nice, you just change the insert to smaller or larger hole and regulate the amount of gas that O2 "sees". Usually if O2 gets too much gas it would throw Catalyst secondary bank efficiency code.After resetting the code by pulling the battery, the code came back a week later. It seems to be doing it more with the colder temperatures.
I wrote Weapon R and they suggested:
"Try unthreading the CEL a little bit and lock it back down. Looks like you might have the CEL too far inside the O2 bung. Sometimes if its too far it will pick up too much exhaust gas and trip the light."
So now I have several things to try. Only problem is I have to go to a garage to have a guy do it.
