Try running SeaFoam through everything?

 

Thats what I was thinking,maybe something is clogged in the injector.

 

idle air control valve

 

My mustang did that and it turned out to be my mass airflow sensor was messed up

 

+1 for the Seafoam.. try it.. even if it doesn't work, at least you have cleaned some stuff out...
