My Monte Carlo has been using more gas than usual lately. I checked the fuel pressure but I don't know what it is supposed to be. Right now I have 53psi, when I unhook the vacuum to the regulater iy goes up to 60psi. Does anyone know what the fuel pressure is supposed to be on a 2004 Monte Carlo 3400?
Thanks
