Re: Please help. '95 Olds. Cutlass Ciera TOO MUCH PRESSURE
It depends on the engine where it is located although most are located between the fuel rails under the plenum. It sounds like your fuel pressure regulator is going bad but it should have between 45 and 50 psi pressure not 16. 16 is ok for a car with a carb. but not one that is fuel injected. You can change it yourself once you find out which regulator you need. You may also want to clean the idle air control motor located on the throttle body and the throttle body itself. This will make the idle better and the car run more smoothly.
