Codes P0171 and P0442

[Neonodd]

Figured I'd post here and hopefully it helps someone with the same codes and issues.

Got the codes P0171 and P0442 on my 2014 Sonic LT 1.8L.

Symptoms: rough idle, smell of gas when starting car, trouble starting car after fuelling, remote start didn't work and surging when stopping at lights.

Fix: changing the Purge Valve Solenoid.

Welcome and hope to hear more.

Those codes and the purge valve solenoid are common issue alright.
And easy 5 minute fix for that many owners can do there selves.
The Sonic 1.8L has a few things that are "wear and tear". . . . but for $300 to $400 for ALL of them are pretty low cost maintenance.
