| Have them try to prime the fuel filter and see if it starts up. You probably had the MAF sensor code for quite some time due to the k&n. As far as the cheapest place to get a MAF sensor...probably gmpartsdirect if you can get the part number for the sensor. Either way, it will cost a couple of hundred. BTW, welcome to the forum.
According to alldatadiy.com the MAF sensor part number for my 04 is 88892543. Alldatadiy says to contact the dealer for the current part number though. This part number is 172 on gmpartsdirect.
