RE: Codes
It is a good indication that the MAF is bad especially since both banks are being implicated. You may want to see if P0101 is also present. Also try running with the MAF unplugged & see if the codes clear.
This may help in clearing MAF troubles, if the MAF is still good:
An incorrectly routed harness-Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components:[*]The secondary ignition wires or coils[*]Any solenoids[*]Any relays[*]Any motors
[*]A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leak downstream of the MAF sensor.
[*]A wide open throttle acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 4-7 g/s at idle to 150 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system.
[*]The BARO that is used in order to calculate the predicted mass air flow value is initially based on the MAP sensor at key ON. When the engine is running the MAP sensor value is continually updated near wide open throttle. A skewed MAP sensor will cause the calculated mass air flow value to be inaccurate. The value shown for the MAP sensor display varies with the altitude. With the ignition ON and the engine OFF, 103 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 305 meters (1,000 feet ) of altitude.
[*]High resistance on the ground circuit of the MAP sensor can cause this DTC to set.
[*]Any loss of vacuum to the MAP sensor can cause this DTC to set.

RE: Codes
yeah those are the only two codes and I disconnect the Maf sensor and the light went off for a second but the car would not stay running without me giving it gas. I started back up with it disconnected then I got a light. Don't have a scanner so I don't know what that code is yet
