I have no cat I am too frugal. my very new looking 02 sensor throws 2 fault codes so. Good luck finding one if I were to do it I would convert it to a dx lx ex si style cat under car cheaper more parts I've seen OE style cats somewhere but they were like 400$ you can pull out the 02 and look you'll see the top of the cat there is no way to clean them. You need an 02 wrench or take off the heat shield the bolts will break and a 7/8 wrench. Use some penetrating oil. A vacuum reading will tell you if the cat is plugged. I think it gradually drops.. Buy two sets of center caps for the wheels I need some also.

I managed to get the heatshield off but didnt have the o2 wrench.it has no hesitation at all when o2 sensor is unplugged.my car has never had the CEL on once yet other than with iacv and o2 unplugged.iv got to find 3 175/70r/13 tires hopefully in used descent shape for the rims i got.

Hopefully one of the local parts places has an o2 socket. i wanna get the stumbling figured out.35mpg aint guna cut it lol

Damn.well i did find a replacement on ebay for $189 might as well.ima save up for it. Looking thru the hole the cat converter filter looked pretty clean.

Cudnt find anywhere online about cleaning it either. wud be nice since it is almost a 200$ sensor.

Actually by looking you cannot tell if the 02 is bad. Mine throws a code. By looking at that cat those tiny holes look to be plugged up. Look if there are part numbers on the sensor it might be just not quite the right one. See vlx build page #7. It needs to be a p09. some say to heat them with a torch to 600 deg and use compressed air ive never had any luck with any method of cleaning. You still havent done a vacuum test it will tell you if that cat is plugged. I get 42 mpg with no sensor.

For all I know, maybe you are correct. But when my 98 DX threw the code, this is what the O2 sensor looked like. BTW, aren't there supposed to be DIY ways to clean them? ... or is that just the spark-plugs? ....

my car has not been throwing any codes at all with any of the issues it has been having. i thought that looked clean for a cat converter. i used a rent a tool wratched to get the o2 sensor off so id have to rent it again to try cleaning it like that. I have a torch and air compressor too.

the o2 sensor has a l1h1 imprinted on it and a few other numbers on it as well cant remember. previous owner said it was replaced by the owner before him at some point. and thinks that from the pcv valves being plugged and something about blow by oil getting into the exhaust then the cat converter.

so basically at this point I may have to get a new cat converter AND O2 sensor?

i think i found a replacement new cat converter and the cheapest i can find so far is 250. not sure if replacing is something I could do or a shop would have to do
is this the right one? theres 2 different cats i keep finding
i think its manufacturer #40352
http://www.partsgeek.com/assets/dima...mb/1083256.jpg

and the cheapest o2 sensor i can find is 189

if replacing the catalytic converter is something I could do that would be great. but I cant find any DIY on it anywhere. especially the vx one

This might be a noob question but i just want to make sure it isnt a big deal.
I got the set of vx rims.one of the tires is descent so i kept it with the rim.went and found two other tires after calling around everywhere and having one of the good tires on my old rims swapped to the new vx rims.i know it all sounds confusing but im just trying to work with what i can afford.all the current steelies on the car are pretty bad so im constantly filling up 3 of the tires.

Anyways all the tires are 175/70/13 and they range from 35psi to 40psi and 44max psi.does the max psi affect the driving at all? Like if they are different max psi will it affect the drivability or are they different just cuz of different brands?

The best situation is to have all 4 tire match. Next best is front and rear in sets. Unmatched tires can affect braking and handling, even if the pressure indicated on the sidewall is the same. Tires from different manufactures even though the indicated size is the same (177/70/13 etc) may actually be different sizes. But if any difference will be notice will depend on the tire difference, the vehicle, and how it is driven.
