2005 Maxima P0455 code after gutting cats and replacing Alternator
My car had the P0420 engine code so I gutting the cat's and put O2 spacers on the 2 O2 sensors behind the cats... within 50 miles of that my alternator went out and I replaced that. Now my car keeps on pulling the P0455 code. I have not replaced my gas cap, but have removed it and put it back on to make sure it has a proper seal... the car still pulls the code after about 75 miles of clearing it.
Could it be because of my gutted cats, or did something else happen that I'm not aware of? If so, what should I look for to troubleshoot?

Something to do with the EVAP system, so its unlikely you gutting the precats or replacing the alternator had anything to do with this problem.

Unless you pulled the whole exhaust system, you might of hit something by the mufflers, that's where some of the EVAP system sits.

check your vacuum line connections under the hood. If you gutted the rear pre-cat by pulling it off the car, you had to pull the intake manifold to get to the two bolts for the pre-cat and might have forgotten to re install them.
