2004 Chrysler PT Cruiser engine problems

Tl*the contact owns a 2004 chrysler pt cruiser convertible. Immediately after placing fuel in the vehicle, it began smoking. While driving 45 MPH, the rpm's increased to approximately 6,000. When the contact eased up on the accelerator pedal, the vehicle stopped smoking and the rpm's returned to normal. The vehicle was driven to the dealer and they performed a diagnostic. The mechanic stated that the turbo was defective and needed to be replaced. The vehicle has not been repaired.

2004 pt cruiser began to idle rough, sometimes shaking the whole vehicle. It seemed like it wanted to stall, but never did. It was always worse after a car wash or during damp, or humid weather. I used carbon cleaners in the gas, took it on the turnpike, as suggested by the dealer, but it continued. After several months, the engine light came on so I took it in. They said carbon had built up in the engine and it was not covered by the warranty because it was caused by the gasoline.
