fuel problem

[good ol diy'er]

car starts and idles fine but after engine builds heat if you rev the motor to about 3000 to 3500 rpm it sounds like it's choking out and not getting enough gas. Not sure if it is the filter stopped up,weak fuel pump,or fuel pressure regulator. But i am going to check fuel pressure just wondering what should the pressure be?

Thanks for all the help so far

Year, make, model, mileage? Just a guess but if this car has high mileage and a clogged catalytic converter, pull the front O2 sensor off for a LOUD drive.

[good ol diy'er]

it is a 2000 sl2 with about 119000 miles but i will try it without o2 sensor

If it's on the original fuel filter/regulator, it's almost 20,000 miles overdue. Only the NAPA/Wix and OEM replacement units provide the proper fuel pressure.

No joke?

No joke. For bonus points, get a filter we don't recommend, but don't be surprised if you eventually pull SES codes P0171 and/or P0301-P0304 (especially P0303 since you have a DOHC) and those codes are traced back to burnt valves from lean fuel mixtures.

Not to mention the maintenance interval for the fuel filter on a 1998-2002 is every 100k miles.

Well hell, just replaced mine with an AutoZone part 800 miles ago...might as well replace that while I've got everything apart now anyway, if that's really the consensus here! I'm embarrassed to admit as well, that the filter I pulled off was original with 260K. Never realized it was a regulator as well. Oops.

Regulator notwithstanding, I doubt there's any vehicle on the road for which a fuel filter, even a stand-alone, would last more than 100,000 or so miles, let alone 260,000. This is why every Saturn that left Spring Hill had a maintenance schedule in the glove box with the owner's manual (and for secondhand owners, they're abundantly available on eBay).

I readily admit to that neglect, but I've been on top of everything else, and she's run like honey for the decade I've owned her...I can live with such a one-time infraction LoL
