So I cleaned the throttle body on my 2007 Chevy Impala LS the other day and since then I’ve had a very strange throttle issue. As I describe in the attached video, whenever I press the accelerator pedal or let the car “creep” past approximately 5 MPH, the throttle rolls on a bit and I can’t figure out why. I just replaced the TPS sensor so I am certain it is not that. Beginning to wonder if it’s the APPS? For those wondering, I DID do the throttle relearn procedure GM recommends, but to no avail. Any help would be appreciated! I also attached the video mentioned as well as pic of the throttle body before and after cleaning. Please take a look at those too as they might give you more context as to where the problem lies. Thanks!!
