Your codes are as follows:
E26 - Shorted Throttle Switch Circuit
F11 A/C High Side Temperature Circuit Problem
F48 Very Low A/C Refrigerant Pressure Condition
I always suggest when a car is this age to note the codes and erase. Code E26 for example indicates a short condition which may or may not be a continuing problem. If you have a persistent code it should be attended to. The AC codes are obvious, you have a leak.
I also suggest making sure your gas cap is properly sealing, #1 cause of check engine light.
