P0101 Fix! Chevrolet Silverado Mass Air Flow Sensor Performance

This is the bros truck. It is a 4.3 v6. There may be similar issues with the other vortec engines! Or any engine really. I didn&show replacing the bolt, but I replaced the bolt to make sure the throttle body could seal to the intake manifold properly. also check your other vacuum hose to be sure they aren&leaking. feel free to ask any questions! please like, and Subscribe if this helped you out! Thanks
