I was driving this car normally but some day on highway the car start stalling and the slow down and after stops working. Scared I thought engine finish. I didn't know this happened is because the regular gas I put in car and the catalytic converter maybe was tired or car didn't like this gas. I called the towing then after I arrived to mechanic he start the car was normal working. The problem happened after i put regular gas not (premium) the mechanic didn't know what is problem he said maybe the car doesn't like regular gas.
