Re: 2002 3.0 engine bad hesitation around 4000 rpm when acclerating.
Changed the fuel filter and no difference. Checked fuel pump pressure and it was good. Took it to a friends Dyno and ran it. At 4k the vacuum pressure dropped to almost nothing. Pulling catalytics off tomorrow. It all I have left. CA unit has 5 of 'em! Wonder if I can eliminate at least 4 and have no computer issues! Because they aint cheap!
