checking fuel pressure 94 3800 v6,? 10 psi ????
:( Ok checking fuel pressure on a 1994 Lesabre 3800 when the gage is hooked up and key turned on pressure goes to 46 psi and after 2 or 3 seconds you hear a "click" from the EGR valve and pressure drops to 10 psi.Unhook EGR and it does the same thing.It doesnt drop slow it jsut drops real quick. Start car and pressure goes to 38 psi and stays while driving.Car seems to run rough at low speed 35mph thats why I was checking pressure. Any idea what the click noise is and why it drops so quick ?
Bonneville 1998 SLE 3.8 v6 series 2,car has 212,000 miles on it and runs GREAT!
