Power Loss
My 2006 Sierra w. 4.8 is suddenly using power. At highway speed the truck will suddenly lose power - the tach will drop to zero then quickly bounce back up again. This only happens when the truck has been driven for a while. It often does this several times in a row, creating kind of a stuttering. At first this only happened at high RPM but now it happens across the range.
Any ideas? Posted via Mobile Device
