Car was running fine, put some gas and problems started. No power ,will not go over 10 miles per hour, could not accelerate and car died after a while. Only restart after the the gas pedal was fully depressed and would not run for long and a lot of smoke would come out. Took it to a dealer they told me the computer needed to be changed. Installed a new computer and no change.

 

Could it be the gas? Just a question.
