I finally got my spacer in for the Skunk2 exhaust, they forgot to include it in the exhaust setup when I bought it new, but when I was taking off my stock exhaust I accidently cut one of the wires on the second O2 sensor on the back of my catalytic convertor. My buddy was mentioning something about one of the O2 sensors controlling air/fuel rations but he wasnt sure. Since I've gotten the exhaust on, I know I have to break it in and what not, but VTEC is being sloppy about kicking in, sometimes it'll kick in at 5200, sometimes not until 6200, and when it gets to 5200, regardless if it kicks in or not it makes a kind of "psh" sound. My check engine light is on, and im possitive its the O2 sensor, but will this problem cease to exist after I replace the O2 sensor?
