okay, so i replaced the fuel filter today and what do you know, the car runs better. This fuel filter had about 1000 miles on it and it was horribly clogged. So now she runs better but its throwing some codes, KOEO memory code 95 and KOER code 12. The code 12 is for Idle Speed Control motor or Air Bypass not controlling idle properly (generally idle too low) - ISC and the code 95 is for Fuel pump: open, bad ground or always on - Power / Fuel Pump Circuits. Any suggestion on how to remedy these codes?

Clear the memory codes, drive for a few days. Then recheck the codes again. Anytime the fuel pump relay is unhooked, key turned on, and ECM still connected, this code will flash. And as stated above, the inertia switch too. But that depends on the year of the car, as some are wired different.
