It was your post I was reading for ideas, Im implementing some of your N/A suggested mods. And what metal plug covers, I honestly havent even looked at then yet?
And um, quick question, my P0420 code popped up, I know thats a inefficency code for the cat, but what are the odds its an o2 sensor? Because with a quick glance yesterday, I noticed the o2 sensor isnt sitting level in the bong.
