For code 26 check fuel pressure with a gauge auto parts rent it. Also check vacuum leaks. Maybe reason one flap closed on airbox. Code 42 is a vehicle speed sensor problem. Have a pro check this because it has to be checked for a bad ecu

Check your battery for condition including load test may be bad. Autoparts do for free. Make sure terminals are clean and all fuses are good. Otherwise let a pro look at it.
