P0496 Buick - po420

Question

I have been told the EVAP purge valve is sticking on my 2010 Buick Lacrosse (75,000). Less than a year ago I was told the catalytic converters were bad and they both were replaced (warranty). Could you give me the likely process and cost for repair.

Answer 1

The likely process will be to replace the cansiter purge solenoid,  The labor up to half hour, the cost less than one hundred dollars in parts
