So today I replace some bolts that were missing on the intake manifold upper to lower. Still need help with hoses under but that’s another post. Anyways noticed a loud whistle noise after I started my truck. Took forever to realize it was the TPS, I would unscrew and adjust n it would make the same whistle noise over and over. finally I just u plugged the battery and let it sit. Fired up and no whistle, has anyone experienced this before?
