P0101 DTC - MAF Out Of Range - Need Help Troubleshooting! I had a DTC thrown today, P0101 which is a Mass Air value out of range code. I had recently pulled my K&N filter & for a regular clean & re-oil (I have a Vector CAI) and also sprayed my MAF with some MAF cleaner. I thought maybe that I had used too much oil on re-oiling my K&N filter so I pulled the MAF and cleaned it again & cleared my DTC using my DashHawk. The DTC is gone, but now the idle is surging 300-600 RPMs above normal. Any ideas? Can someone with a CAI kit and the ability to monitor Mass Air flow (via Scan tool, DashHawk, etc.) let me know what value it should be at idle. I am showing 16-18 g/s??? Just wondering if my MAF sensor is shot or what?

most stock cars are around 3-5g/s not 16 so best bet is aa bad mass air flow. Make sure the sensor is not backwards first and next time give the air filter a few hours for the oil to dry before reinstalling it.
