Okay... here's the situation... I've now failed the inspection sniff test three times. This is getting ridiculous...
Here's what we know so far:Here are the numbers:
- Replaced spark plugs
- Replaced spark plug wires
- Replaced O2 sensor
- Set timing back to 10 degrees
- Using a FM high flow cat (that does work!)
- Using 87/89 octane gas from 7/11

The first test was yesterday afternoon... the second was this afternoon at about 3pm. The third was at 5pm.
This morning I drove from Frisco to Texas Stadium to perhaps clear the cat of any contaminants. The cat and the car definetly were up to operating temp for the second and third test.
Perhaps pre-detonation? The inspection tech was very helpful but there was only so much he could do. Their mechanic walked over and offered his help at $79/hour. I politely said no thanks.
Do you fellas have any ideas? I'm at a loss here...

Perhaps???Originally Posted by Found this on the ::Batman:: board...
Just did the 'ol Seafoam treatment... and much to my dismay, the stuff came sputtering out of the header where the four pipes meet into one. Perhaps a problem?
Time to get it welded...

Lightness? What's that? I drive a PRHT!
my girlfriends 300zx failed for nox and i replaced the vacuum lines on the intake and it passed so i would check for vacuum leaks. also make shure they are using a fan to simulate road wind, if they don't nox increases with temprature so you could be failing due to cylinder head temprature . nox and co are related so a low co reading is almost always related to a high nox and a vacuum leak
They were using a fan on the front end...
How fresh is your oil? Clean oil can make a big differance.

Okay... small update:
So far - new plugs, wires, 02 sensor, used working cat, a can of Seafoam, a tankful of Chevron Premium, a bottle of Guaranteed to Pass...
I'll try again later this week after I burn through this tank.
Make that 4 times that I've failed the test... oh so close... and it even gave me a retest.
Yikes... where do you go from here? In California, it wasn't uncommon for people to get a PO Box in a county that doesn't sniff annually. Probably not very legal, but doesn't seem much different than Bush listing TX as his primary residence rather than DC to save on his taxes.Originally Posted by Treibenschnell
Have you tried taping a $20 bill to the tailpipe and seeing if that helps you pass? Wink wink, nudge nudge, know what I mean?

How about a stock cat instead of a high flow?
Yea that's what I was thinking my old POSII still had the original cat and 162K on the clock and it passed with flying colors....Originally Posted by Majik
What were todays test results???
Sombody around here with a 1.6 that has recently passed inspection havve a they would be willing to loan Bean??

Well post up the test results Sparky!
I do, but he opted for the High flow cat I had sitting in a box rather than waiting for us to find time to swap out for the one on my car. Perhaps we can do a swap this weekend?Originally Posted by POS Racing
I've got a high flow on Sunny and no problems. I do, however, have a cat off of Speedie Jr that you could try. I really think you should consider getting the exhaust leak fixed, or replacing the header. I could probably come up with one of those, too! Too bad you're such a TCB.......

Perhaps I can talk you into coming by tonight... I can have them switched out in a flash.Originally Posted by Titus
Besides, this way I can put some hot time on the way to and from Mineral Wells this weekend.
Well you know me... got to clear it with the first.Originally Posted by Treibenschnell
