No but you should be using 8mm wires. That won't fix your prob but these vehicles require 8mm. As for your code, proly bad o2 sensors but I don't know crap.

Why do they "require" 8mm wires? I've heard people who swear by them and those who say don't bother wasting the xtra $$ on them. There are no performance gains by using them. So....Why do I NEED them? School me
