Hello I own a GMC 2001 Jimmy I recently tuned up this vehicle changed the fuel pump and filter as we'll as transfer case. The truck still gives me a sluggish rough drive when driven above fifty mph or****** as if loosing power please give a brief diagnoses of this vehicle problem asap. I've read something to the affect that this car has a passlock code or a pemlum switch in which I may have to take it back to the dealer in order to have the truck driven normal again? Is this true? You can also email me at 1blackman80@gmail.com, if you have great information that can help me, I work 2 jobs and I definitely need this truck fixed asap im so exhausted. Thank you so much.
