Focus Purge Valve Causing Engine Stalls?

Each car has an EVAP system that traps fuel vapors before they escape the gas tank. Those vapors are stored in a charcoal canister and then, in certain situations, a purge valve opens and allows some of the vapors out to be burned off by the engine.

But what happens when the purge valve sticks open?

According to a proposed class-action lawsuit, a stuck purge valve is causing the 2012-15 Ford Focus engine to run rough and sometimes even stall. Additionally, the valve is causing problems with the gas gauge. This isn’t the first time we’ve heard of this issue:

“My vehicle’s fuel tank is compressing due to a faulty vacuum purge valve requiring a new tank, fuel pump and purge valve. This issue has caused my vehicle to stall in freeway traffic @ approx 60 mph and to stall in stop and go traffic.2012 Focus owner

While we wait to see what happens with the lawsuit, let us know if you’ve had any issues with a struggling engine or stalling.
