6.0l Flashing Check Engine Light

[03bluess]

 

I have a silverado ss with the 6.0L my check engine light is on and when kicking the truck down there is nothing there it feels like i am drivng a 4 cyinlider. i checked the code and the code reads massaive air flow and miss fire. i brought it to the dealer they told me it was my o2 sensor before the cat. i replaced it and it still does it. Has any one had this problem? please any information would be very helpfull. thanks. Dave

Is your mass airflow sensor really dirty? Clean your MAF and disconnect your battery.

A flashing CEL means stop. Driving further can damage critical components (like catalytic converters). A solid CEL mean check when possible but isn't such an immediate cause for alarm.

 

Pull the codes and fix it before more damage is caused.
