yea I know my o2 has been bad from the start. But when I say rich I mean really really rich. I pulled the spark plugs today and those things have no gap in them because of the carbon buildup. I only had those in for a week or so. Also, my spark plug wires came apart in pieces today as I was removing them. I was reading my Integra shop manual today and it seems that the richness problem could be caused by that evap purge system that comes with the gsr. Only problem is that I heard you have to hardwire the evap system to the ecu for it to work. (because the civic doesn't come with an evap system) Anyone know anything about this? Appreciate the help fellas
