P0174

New air filter on Tuesday night.

CEL on Thursday PM - she's throwing one code: P0174 lean on bank 2.

Based on what I've read here, new air filter often equals dirty MAF which can result in P0171 or P0174 - correct?

I'm thinking the correct course of action is to clean the MAF per the instructions on the forum and see if that clears it up.

If not, I need to start looking for vacuum leaks.

Sound about right?

Dirty MAF will show less airflow and therfore PCM will inject less gass than actually needed - thefore a lean mixture.

Makes perfect sense to me.
