RPM does not reduce when shifting
I see this is quite old but I just purchased a 09 ss that hangs after gas is released and clutch is pressed. What ever rpm your at when you push the clutch in it just hangs there for a second or two. Looks like I don’t know how to drive a stick been driving one for years never had a car act like this

I have had the same issue since new on my 08 HHRSS Manual. Seems to do it worse when the engine is heat soaked, like in a drive thru line then leaving. Rpm's hang high after the throttle is released for a couple of seconds. Did it before and after the Stage kit install in march of 08, does it now but a bit more often at 91,000 miles. I have replaced ECM, ECM Program, throttle body and throttle position sensor, gas pedal assembly and electronics, MAP sensor, and checked all lines and hoses. Seems like its something in the ECM programming, as an emissions cycle or something. Have not been able to find anything else. SS runs great and has has no other issues. If anybody else finds the cause please advise.
