My trailblazer dies when at complete stop. Codes are p0442, p0300, p0102. on 2001 Chevrolet Blazer

When starting I've got to press gas pedal to get it to start. When it's started and driving it accelerates on its own. And dies when I come to a complete stop.

Blazer or Trailblazer? I see both posted!

Depends on if it's on the road or the Trail.

Depends more on which vehicle we need to guess at.

This one is going to need a scanner to check live data for the mass airflow ciruits, evap operation and engine misfire. No way to guess at it! That would do any good that is.
