thikstik Posted February 5, 2012 Report Share Posted February 5, 2012 I had a low tank and while idleing heard my fp make a bit of a howling noise. It is OE with 238k miles. I put gas in and no more sound , but have noticed full throttle is a bit weak. I tested pressure at idle..it is around 35 line off. I need to test drive at wot and get a reading, what do yall think it should be? Thanks ps- its a 1994 regal 3.8 Quote Link to comment Share on other sites More sharing options...

The tester i have does have a bleed line and when its opened the pressure drops alot, but there's nothing to compare it to. thanks for the spec.
