P0172 code

My car is throwing P0172 code, I can't pass smog unless i fix that problem. Anyone know how do I fix it?

Vacumn leaks will usually throw that code. Spray engine starter fluid all around any vacumn lines in ur engine bay, if the rpms start to go up, you've found your leak.

also check your MAF and clean it

a vacuum leak would cause it to run too lean that is not the issue in this case dont waste your time looking for a leak. if you havent already removed the black box for the cpe do it now and reset the ecu my guess is this is your problem
