Well, kicked the cat today, and there was no rattle or blatent givaway that it was in need or replacement.
Could it be the fuel filter going bad/ is bad?
Where is the fuel filter located so that I can check it?
I appreciate all of your help guys!

If you own a 93 with 125,xxx miles and you don't know the location or the condition of the fuel filter........then it NEEDS to be replaced.......end of story!

Kicking the cat is not a reliable test. Although it may be fun, it will not tell you the condition of the cat.

You need to do a back pressure test to determine the condition of the cat.

90% of the time, kicking the cat will produce an accurate diagnosis. If it rattles badly, it DOES need to be replaced. 10% of the failed cats I've seen made no noise. It'* a quick test you can do in your driveway.

Not trying to disagree with you willwren, but a "rattle" test is not 100% accurate. I see plugged converters on 30,000 mile cars that make no noise at all. I see plugged converters on 140,000 mile cars that make no noise at all.

The "rattle" test is just a simple-means nothing-test. The O2 sensors themselves rattle by desighn. Not loud, but they do jingle.

Back pressure is the only true method to test for a restricted converter.

ok, I need to replace my fuel filter, but where is it?

He has no O2 sensor in his cat for that year. The 'kick test' I mentioned is a good 'DRIVEWAY' check as I mentioned earlier, and CAN give an indication ot trouble.
Furthermore, on a car of that age, if the Cat is stock (oem crimp welds) it more than likely needs to be replaced.


Puddy, your fuel filter is just on the inside of the passenger frame rail about under where the RF passenger'* feet sit. Quick release clips on fittings and a 10mm for the retainer. YOU WILL STINK, so wear grubby clothes.

In general, if the problem seems to get worse with higher temps, it'll be your cat more than the fuel filter.

ok, now we're cookin with gas!
thanks for the info will, it makes this task a lot easier.
