My trailblazer dies when at complete stop. Codes are p0442, p0300, p0102.

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

Depends more on which vehicle we need to guess at.

Trailblazer

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.
