after warming up car starts missing really bad. wont hardly get off idle. once reved up it runs ok. sounds like ignition but the only code is the P2009. idles terribly. switched the two solenoids, no help. it just feels like ignition but no codes. Help!

 

Have you inspected and tested the intake manifold runner actuator?

Have you inspected and tested the intake manifold runner solenoid?

 

Replaced plugs, wires, coils and one vacuum valve. Runs like a champ.
