Check engine light came on with EVAP code coming up. Took it to a pep boys and they came back to me with the canister vent valve needed replaced. One day later the light was back on with along with a surging in the engine. Recharge light blinks in rhythm with the surging. It is now at a ford dealership and they drew up the same code for the EVAP. They haven't pin pointed the issue and said that they need to remove exhaust and fuel tank to check a fuel vapor valve. Issue unresolved as of yet.
