Cannot help you finding out what codes mean but if light flashes do not drive it but it is ok if it stays on for a while.

P0300: Random/Multiple Misfires
P0732: Gear 2 Ratio Incorrect
P0731: Gear 1 Ratio Incorrect
P1126: Manufacturer-controlled Air-Fuel Mixture Metering

It’s unlikely (but possible) the computer is going as it is one of the most reliable parts on your car. Those other problems/codes listed above should be checked first before suspecting a bad computer.

P0731 and P0732 are transmission-related; perhaps transman is lurking and can give you a better idea on those.
