My car didn't pass smog again. I replaced the o2 sensor, plugs, working Afm, working cat. Still didn't pass. Anything I should check?

Take the paper work to a shop , if its too much$$ just get a special smog

[e30james325]

was your car really warmed up?

[///digitalme]

Yeah drove around for about 1 hour before hand I don't know what else to change

[blocke]

Doesn't look like the cat you used was good. Compare your numbers to the ones I posted with a brand new cat

[///digitalme]

I'm going to take it in to check and do a diagnosis unless.someone I borrow someone's exhaust

Just replaced the cat with a known working one. My old cat had a hole on the bottom and was completely gutted it was just a pipe . Now my car is really quiet , will change my Afm and spark plugs and possibly o2 sensor in hopes it will pass. I have a free retest chance. Anything else I should change

Did you seriously try to get smogged with a gutted cat? And you're wondering why the NOx levels are high???

Nvm, just read that you had no idea.

Are you getting the new cat hot? Try some high-speed freeway runs.

Took my car to a specialty shop that fix gross polluters was told that it.was the cat but they wanted 450 for the cat and a protest. So I'll be getting another cat this time new and I'll take it from there

Now that you know for sure it's the cat, you should shop around. I got my Magnaflow cat installed for like $300 bucks. And a pre-test would be a waste of money at this point. You already know ti's the cat, so once a fresh one is installed, you should pass with flying colors.

the muffler shop i went to last week said 185 for the magnaflow cat and a generic brand was 160..ill see if i can find another muffler shop that will beat that price

Some basic info on why the cat fails...if you add ZPPD to your oil you should watch.
