Engine Performance problem
2004 Chevy Silverado V8 Four Wheel Drive Automatic 95000 miles
i have tried to perform a tune up. On my truck, it has a 4.8 v8 and I have replaced plugs, wires, air filter and I can not find the fuel filter. The hanes manuel states that 2005 has not fuel filter but as you can see I have a 2004. I have checked by the frame rail from the gas tank to the fire wall. Is there a fuel filter? And what else do I need for a tune up?
