So my truck is a 1997 350 vortec el60e z71. and while im driving down the road and the truck gets to cursing speed. the truck will start to shudder. when you step down on the throttle is goes away. also the fuel pump is extremely loud. would y'all say the the fuel pressure is dropping off and its starving for fuel?
Truck also has code P0430 Catalyst system efficiency below threshold bank 2. so im guessing possible bad cat?
