This condition may be due to an intermittently sticking fuel level vent valve on the fuel tank allowing fuel to enter the evaporative emissions system lines and evaporative emissions canister during refueling. If the customer states that the drivability symptoms occurred after recently filling the vehicle, replace the fuel tank \(9002\) and evaporative emissions canister \(9D653\). Refer to Workshop Manual \(WSM\), Section 310\-01 to replace the fuel tank. Refer to WSM, Section 303\-13 to replace the evaporative emission canister.
