Default p0101 code
Could the debris on the maf cause this code? Someone before me installed the air filter incorrectly.

Interesting quotes from the GM manual

• Inspect for any contamination or debris on the sensing elements of the MAF sensor.

• Inspect the air induction system for any water intrusion. Any water that reaches the MAF sensor will skew the sensor and may cause this DTC to set.

So it could well be that..
