Hi, problem is crank sensor is constantly going out over a very short time. This is my 6 replacement in less than 6 months. We have put a new pigtail harness, that didn’t work, coil wire good. Also sluggish taking off, when you put vehicle under load it’s like riding a bucking Bronco, going up hills when you have to give more gas it bucks, jerks, all the time going down the road. Eventually blowing the cam shaft sensor. I have changed so much on this vehicle. Bought a Re manufactured ECM and programmed at the dealership. That didn’t help. The dealership at this time cannot tell me what’s wrong with my Tahoe. It’s mind blowing!!! My vehicle feels like you know when something is not completely grounded, that’s the way it feels when it starts jerking , dies, and eventually blows the Cam Shaft sensor!!! Something that the dealership can’t figure or me. Please help!! I need some piece of mind!! Please, thanks
