Earlier post

If you look back, I have had some concerns about my fuel delivery system. Yestarday, I found that my fuel pressure would peak at 6 1/2 pounds and slowly return to 4-5 pounds. After a little while, it would drop to 3 pounds only to a rise and fluctuate between 4-5 pounds again. The only thing is it runs fine at highways speeds. Now at idle, you can tell when it drops (starts to get rough). I am starting to think that the 6 pounds could be causing that richness I see after sitting for a minute. Possibly causing issues with the needle and seat, yes? I would assume, the the pump its self is on its last leg, huh?

Thanks

Only because I've done everything else to it. The plugs them selves look good too.
