did the code check, code 67(6 long flashes, 7 short flashes)

Has to do with cat converter. What does this mean? Is it the sensor going into it or the actual cat itself?

I replaced the stock cat with a magnaflow direct fit high flow cat a few months ago, fit perfectly. I did notice the sensor was a little dirty at the time, but I wiped the outside.

So just recently the light came on. At least it's not a bigger problem.

 

Code 67 generally means the cat is bad, but before replacing, check for an exhaust leak somewhere between the primary and secondary O2 sensors.
