Last night all was well. woke up this morning with a car that stalls and wont go beyond 3rd gear when it is moving. below are the symptoms

Codes 0069, 0151, 0102
Stalls when starting, wants to stall at stops

cleaned MAF & MAP

I did find that the airbox was not put together right last oil change when i got in there today. it was just kind of lose and barely hanging on, but somewhat open. Was planning to pull intake off tomorrow to check for debris.

Any ideas? This is my wifes car... getting an earful.

 

For WIW here are the definition of the 3 codes.

P0069 Manifold Absolute Pressure Barometric Pressure Correlation
P0102 Mass or Volume Air Flow Circuit Low Input
P0151 O2 Sensor Circuit Low Voltage (Bank 2 Sensor 1)

 

I also on a hunch clicked over to the environment screen on the MMCS... it shows no altitude or barometric pressure...

could my ECM be shot?

 

That would be related to P0069
Also P0151 indicate you are running lean, too lean to sustain idle.
Make sure all electrical connectors are in properly around the air box as it was loose, it could cause a harness to disconnect.
Make sure the air ducking is solid downstream of the MAP sensor other wise you could be sucking unaccounted for air thus running lean. That apply to all hoses also.

Things rarely die overnight just human do.
