The allowed CO% is .98 and 1.08 for two different speed ranges, and I got a 4.0 and 3.98 respectively. I'm bringing my car in for a full tune-up this week, valves, O2 sensor, fuel filter, etc. Anyone have any ideas on what would cause such a bad CO%??? Any help would be greatly appreciated. Thanks.
