PONTIAC GRAND PRIX GAS PROBLEM

2003 Pontiac Grand Prix • 180,000 miles

My car started shaking bad every time I press the gas. When I let off the gas nothing happens, what could be the prob?

How long since a tune-up? Are there any applicable trouble codes? Some of the national brand autostores will check codes for free. Also, use a gage and check fuel pressure.
