My check engine light came on a few days ago. I took it to Advanced Auto Parts and had them run a test. The test came back w/ the following errors P0101-MAF or VAF A CKT Range/Perf. P0171- System too Lean (bank1). P0300- Random/Multiple Cylinder Misfires detected. I have done some research and learned that the sensor needs replaced. Will this fix the problem? If not what do I need to do next? Iam trying to save money by fixing it myself and avoid a trip to the dealer. Any advise/info would be greatly appreciated!
