Car is throwing CELs p2069, p0171, p2070. Upon changing gears there is slight hesitation in the rpm's. Best way to describe it is the gears change and the rpm's drop slightly before it revs back up even while giving constant gas. it's a 05 AT. anybody have these issues or know how to fix? alson just installed the AEM CAI about 4 days ago. I checked all the vacums and connections and everything is tight. I have no clue????
