Lately I've been getting this code about 1-2 minutes after I start up and drive away. Its always preceded by a hesitation. I have the Aeroforcetech guage so I just clear it and drive. I have the TBSS with 6.0 LS2. Any pointers on what's going on? Does the MAF need cleaning or maybe replacing?
Thanks
Kev

They have MAF cleaner at most auto part houses, but be careful not to break the fine wires inside. Did you check the plug and wires?

Yes, try cleaning the MAF sensor with MAF cleaner
