O2's and EGR.
See if the ks code returns after the above 2 are fixed.

The car runs fine, or seems to anyway, no knocking hesitation or anything of that nature, it just sat for a year only being started with minimal driving once a month probably.... i will start with the O2s and let yall know.....thanks for the help!!
