I'm guessing it was a mixture different things, the valve cover, ignition coils fouled up plugs, air leak. I replaced a good amount of parts and she's running great except the cat issue. Ran her through ISTA and the cat is the only issue I'm having. I need to get this done, I have emissions testing before the end of the month.
