Question about 1994 Plymouth Voyager
Posted by Anonymous on
Fuel pressure regulator
Posted on Jun 10, 2010
The rich fuel problem is not constant, implying the problem seems to come and go. Remove and inspect the spark plugs to determine which fuel injector is giving too much fuel. Rich fuel will result in excess carbon build up on the spark plugs. Pour fuel injector cleaner in the fuel tank and see if this corrects the problem. Samtoler claims its's the fuel pressure regulator, which I disagree. If this were true, the problem should had been constant, not random. With faulty injectors due to carbon build up, the carbon will come off at random times, then come back on, resulting in poor atomizing of fuel at random times.

need to pull to determmine what fault codes are present. But from what you have indicated I have experienced a defective mass air flow sensor. but the fault code will verify this.
