Pulling out of a driveway to center lane and then merging with traffic, the vehicle would not accelerate. rpms would flare, but car had no power as if engine was not getting fuel. this would happen intermittently. vehicle was taken to dealer who stated gas had gotten into an emissions part in the fuel take, stating it was caused from over filling the tank. vehicle owner told dealer that the tank had never been over filled or capped off while fueling the vehicle, so the part must be defective. vehicle owner still had to pay to replace canister close valve. dealer claimed that rpm flare up and loss of power was caused from the clutch slipping, although rpm flare up never occurred while dealer had the vehicle. at 100,000 estimated miles, the same fuel valve needs to be replaced again, and to date, the fuel tank has never been over filled. *tr
