We had a diagnostic done on the vehicle because of lack of power. It came up o2 sensor, egr valve and mass air flow. We put a new o2 sensor in and cleaned the mass air flow. It ran, but the same way. So the next day we changed the air filter and recleaned the mass air flow. When we went to start the vehicle it would not start. We called the auto parts store to order a mass air flow sensor, and they told us to take the o2 sensor out. If the vehicle started up, then the catalatic converter was clogged. We tried that, and it worked? Are we on the right track? Coulod there be more involved
have the same problem?
