Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is***** to JustAnswer.
Sounds like they left a line off, or poor connection. If the purge solenoid is pulling in air instead of evaporative emissions as it should, it will lean out the engine as the ECM is expecting fuel vapors not fresh air! I would advise to take it back and have them check it over for whatever they may have missed. It is unlikely these codes are not related to the recent repair.
