I have a 2003 gmc sierra 1500 (base model) and I've been experiencing stalls when I attempt to start my truck. It always starts, but it struggles. The OBD II code is p0455. I've watched your video about the purge valve and was curious if you think this could be the problem with my truck, too. Just curious on your two cents and if you knew anything specific with my vehicle model. Thanks!
