Failed smog!!!! Help!!!
I knew i had to smog my car so i figured i didnt want to mess around with having to go back so, i put on all the stock Greddy stuff the way it was ment to be exept for the down pipe. I even got a new 3" cat put on. I failed in the NOx by alot, the max is 726 @ 15mph, and 786@ 25mph, but i was 1611 and 1604. What should i do???

I just went down to the auto parts store and picked up a new 02 sensor i figured it wouldent be a bad idea to replace it. My timing was set to 8 and stock is 10 i thought?

Any other hints?? Does any one elce think my idea will work??? Could my cat be so big that the miata wont heat it up. And if so do you think that pulling a wire off a plug and letting raw fuel into it for a few minutes before the smog check would help it heat up???

I too failed in the Nox section about a week ago, retarding the timing from 14 to 8 actually made my #'s a bit worse. I plan on getting my car onto a 4 gas analyzer next weekend and hoping for the best.

I drove it pretty hard on the way there and let it run in the parking lot and the smog guy ran it at 2500 rpm for 5 min or so before he smoged it. I just put the new 02 senser in and it seems to run totaly different "good" so ill wire the waste gate open when i go in. I also put stock temp plugs in at the stock gap.
