I was ridin down the road... CEL comes on.. car starts running like ****, so i took it to the chevy dealership and they said the cam sensor went out of calibration; and that they had to recalibrate it(cost me nothing). Anybody know anything about this?? Also my Barometric Pressure Sensor is throwing a code(P2228), i figured it may be the intake i have on the car(K&N). Is that normal?

 

its not the intake try cleaning the baro

 

^will do, thanks

 

found a vacuum leak. the code went off. Thanks.
