car idle surging

[razortalons]

Hey guys i do not mean to post all my problems at once but ther is also one to two other things that i need help with my car!! I recently also replaced the head in my car!! Ever since then certain time i get an idle surge!! My car is stock except for a k&n air filter!! I have replaced a crack manifold in which i thought was causing it!! I have even replaced the o2 sensor!! I think this is also causing my check engine light to come on!! I have had a diagnostic done and they said it was the o2 sensor but sinc i replaced it i still get the same results car idle surges from time to time and my check engine light stays on!! the car rund great outside of those minor problems!!! Thanks in advance!!!

sounds like another victim to the idle control system malfunctioning. I'm suffering with the same thing. Get another check of the engine and see what code it is. The ICS code I got was P0505. I'll keep you up to date on what this repair involves. I'm getting in taken care of this week hopefully...
