    Default 2005 Suburban - Reduced Engine Power

    Hello Everyone, I am new to the forum, and I am looking for some help. I have a 2005 low mile Suburban. This is my 3rd Suburban, and they have all been great for our family until this one. I have the "Reduced Engine Power" that many have had. I have been fighting this for a year now, and I don't want to pour more money into it. I am hopeful that someone can help. I have replaced the throttle body, wiring harness, cleaned all grounds, and have gone through a few throttle positioning sensors. The code keeps appearing, and our main family vehicle is just sitting in the driveway. Can anyone help? I thought about trading it in, but I cant pass along a lemon to someone else. Thanks, Steve
