Had check engine light with codes p0301 -p0302. Checked coils and they were cracked. Replaced then with new ones reset code and the same codes came back. Could a bad oil seperator cause these coes to come on. The plugs were covered in oil. and now i have new codes p1128 and p1130.

Could be the seperator. Check for vacuum at the dip stick,anything over 4.5" of H2O indicates a bad seperator. You said the plugs were soaked in oil,do you see oil leaking around the spark plug tubes?? this can also cause fuel trim issues.1st step is to check vac.@ dip stick ,then smoke test the intake.,also if you can post your fuel trim #'s & data from you scanner , that would be helpful. What type of scanner are you using??
