LS 4155 codes

[jnails]

Hi, I,m new to the forum.
Have an LS 4155 throwing f11-s157 and f18-s1064 codes, lack of power and shutting right down at times. Did a little research and maybe need a computer update?
Didn't know if anyone else had a similar problem.
Thanks

I'd call LS or dealer and ask what the codes meant. Are these codes off the dash or are you using a code reader through the OBD port?

Off the dash
