How do you know it's getting clogged?
Who's telling you it's clogged?

are you running rich? If your cat keeps getting clogged there's an issue with your engine that it keeps emitting high hydrocarbons, carbon monoxide,and oxygen, more than should be processed by the catalytic converter.

Are you sure its the cat, it might be the o2 sensor thats bad

champstar

what makes the engine run rich

uhmm a bad o2 sensor, vaccum leak,spark plugs wires,spark plugs,cap and rotor, basically your getting too much fuel thats not being burned


when is the last time you did a tune-up?

if ur clogging in 4 months you should see if ur running rich. ull get black smoke out your exhaust. u running 2.x or 3.slow?

i just cahnged my spark plugs about 3 months ago (NGK Iridiums)

would o2 sensor spacers work to lean out the fuel mixture and solve my problem?

Josh99CL

If you're talking about the secondary O2 (after the cat) no that won't do anything to improve the situation. All that sensor does is throw codes if your car isn't converting enough exhaust. It has zero influence on any changes to how the car runs.

DaInFaMMuS1

Yes it does have something to do with performance, if you're not converting enough exhaust at the correct emissions level the O2 sensor will send a signal to the PCM to make the car run leaner to decrease the amount of emissions

^exactly if it didnt do nothing but read then it wouldnt be there.

Its as important as the first o2 sensor

champstar

so will an o2 spacer solve my situation?

SupraManAG

stay away from that crap. replace your o2 sensor to get oem spec. Anything you do to modify the o2 sensor is only going to complicate things. The more complicated you make things the harder and costlier its going to be to fix.
