Shakes or Wobbles problem
1993 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 210000 miles
my 93 grand prix started idling erratically. I changed the plugs and wires, that didn't help. Then I checked the fuel pressure: I hooked up the pressure gauge and turned the ignition switch on. The pressure went up to around 45 psi (which is where it is supposed to be) but then dropped slowly all the way down to zero after the fuel pump stops running. It is supposed to hold steady. Does that mean I need a new fuel pump
have the same problem?
