Code read is P2004. Replaced both Intake Runner Valves. Replaced Idle Air Control Valve. Driving runs fine. At idle, acts like it wants to stall at times but doesn't. What's next? Do I have to replace the whole air manifold? Any suggestions? Maybe a stuck valve door in manifold?

check for air leaks or blockage between air cleaner and throttle body clean throttle body plate on both sides and iac hole with choke cleaner, check for worn throttle body shaft. check for vacuum leak, air leaks like a grommets on engine and or duct work.
