So, driving home last night the check engine light started flashing. I happened to have my trusty scan tool handy so i plugged in.

As i was watching the light stopped flashing and just went to solid.
I know what rhe codes mean, but with that many misfires, i would think i would notice. But Shrek was cruising along like nothing was wrong.
I have had intermitent instances of rhe CEL flashing whike under load.
I believe rhe fix is new cats. I have ca emission set up on my 4.0, so need the twin little cats.
Everywhere I look, all I see is the cats that are not leagal to sell in CA. If I were to want to put on the actual aproved ca cats, where would I find them?
And if i put on the ones that are not ca approved, does anyone know if there are performance issues with them??
