I just recently have acquired a 2001 maxima gle with an odd problem that i havent been able to fix. Basically what happens is in a cold start the car goes under 500rpm and stalls out. The check engine light is on and it reports a broken IAC Valve, which has been replaced, and the light is still on. During a warm start it works fine.

Has anyone else experienced this problem?
If you have any help would be appreciated.
