Default 85 sedan deville error code E26 and F11 and F48

85 sedan deville error code E26 and F11 and F48. How can I get these codes to go away? Plus the service now light comes on until I give it a little gas.
Thanks for any advice,

Get a factory service manual to trace and diagnose each code to repair the cause. You can disconnect the battery to erase any that are history codes, but until the reason is repaired, codes will come back.

Default 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.
