I plane on doing plugs, wires, cap here soon.

I belive I may have found my problem to the code P0420. I was looking at one of the o2 sensors and the plug that come from the o2 sensors is melted it could be causing a short inside the plug.

Sorry for all the question beised AC Delco what is another good brand of spark plug wires that is good for the blazers. I plan on getting AC delco , rotor, cap and plugs.

I have had good luck with the Belden Premium wires from Napa. I also didn't have any problems with their premium cap/rotor either on my old '00 Bravada.

I'd get that connector fixed asap!
