Welp, yesterday I replaced my test pipe with a Jackson Racing cat and took it to the shop to get it inspected; unfortunately, I passed everything but the NOX emissions. So now I have 15 days to figure out what's wrong.
Anybody had the same issue? I need to figure out what's going on here... I'm not very knowledgeable about any sort of emissions testing.
Thanks for any help!
Car is a 1.6 NA.
How close were you to passing, and do you have your timing set back to 10 degrees?
Reset the timing and get a stock cat... Titus had issues using a after market cat too.
Also, don't forget to run around and get that cat hot before you go in.
I've heard of a few JR cats failing too.
My FM cat has passed the last 5 years. Looks like Titus has one in the classified. Also JonWag's parts car may have a stock one.
Good luck
Timing is set at 14 degrees; I don't have a timing light or anybody to help with it at the moment. Is it that big of a deal?
Also they said I was double the passing level of emissions...
$20 says it will pass if you set the timing back to 10 and re-test with the CAT hot.Quote:

Stop by the house one evening and I'll help ya reset it. We can even mark the CAS with both 10 and 14 degree settings so you can move it back & forth with ease.

the cat you got from me was supposed to be a stock Mazda cat with less than 1,000 miles on it
my 93 with 123k on it passed with flying colors
so if I stupidly gave you the JR cat that was in the same box, sorry, come get the right one
anyone know if the stock cat has heat shielding on both sides?
the one I have in my hand has that
the one Joel got from me only had shielding on one side
Joel, does it say JR on it?
and I have a timing light, but am not available till Monday; between out of town and appointments all over the metroplex, just got no time till Monday
I left you a message, but you no answer :(Quote:

Took it to Kwik Car again, and they said they weren't getting enough exhaust flow, probably due to the leak. So I took it to the muffler shop, and they put it on the lift, THEN asked me if I had gaskets. I told them I thought they had them (I asked yesterday). Nope. So I had to run like the dickens to the nearest import car center (that Nealb told me about) and they don't have them... so I had to go home, pick up my test pipe, and bring it back so they could find SOMETHING that would fit. They found a pair of gaskets that would work, so I bought them and went BACK home to pick up the Miata, then took it and got the gaskets put on, THEN went to Kwik Car once again, this time actually passing inspection.
And yesterday was even worse.
I have a very sore throat from screaming at traffic.
So anyway, I finally passed inspection (luckily I didn't bet against Titus) and I guess I now need to return the cat and install the test pipe again until I can buy another cat. I also need (desperately) to readjust the timing again. I feel like I have 50hp.
Thanks for the help, guys.
:drive:
If adjusting your timing back affected it THAT much then you probably have a bad crank pully. I have a bad one on the Spec. The inner & outer segments are misaligned which makes the timing marks off.
The car wouldn't even spin the rollers for the inspection until after I set the timing by ear - it passed. I have the new pulley but haven't put it on yet.

What happened? The crank you got from me was good, I thought you took a good pulley as well.Quote:
