I just don't personally trust ANY Bosch plugs.

As far as the cats being clogged do you have any power loss when you are really pushing it?

And with the intake gaskets; it seems like you would have a Lean code if the vacuum leak was bad enough to be causing the misfire.

Have you done anthing with the EGR?

so i think i narrowed down the issue. i didnt install the parts i ordered yet. i tested the cats temp yesterday using a laser gun. BANK 1 ( which i had a heater code for) was 302 F. while BANK 2's car was 180. magna flow cats will be ordered soon.

Please forgive my ignorance, but which temp is the abnormal one? I assume since your referring to a code, the 302 F one is abnormally high? Also, what heater code? One of the many DTC's?

mine yukon is misfiring and sputtering like crazy during the first start of the day but after it warms up its fine the rest of the day. i changed the plugs and wires, feul pressure regulator, had a fuel pump failure and changed it, and a few days ago it threw the p0420 code. if it was the cat wouldnt it make a loud "rattle can" noise. i have used the rubber mallet to bang on the cat to see if it rattles but i got nothing.
