Yes, the third one should be dated 06-09-2006, not 2004. Yes, it's been two years and you'll notice that back in 2004 (after the new cat was put on), the CO levels for both 15 MPH and 25 MPH were very low at 0.01. The oil is the same oil from 2004. I never reached 3000 miles, so I never changed it. I'll change the oil to see if that helps. The spark plugs on it are fairly new (changed in 2005). They were previously fouled because of the short distance driving. I'll probably check them out as well.

Does anyone know a place where I can get Part #16578N4201 - Air Intake Rubber Boot with Nipple Part #25420N4310 - Fusible Link Cover (I need two of these). The dealership doesn't want to order the intake boot for me because they say that even though they use the right number, they get a boot without the nipple fitting for the return gas. Supposedly, it's a J-Code item which I guess means that dealership is stuck with it and can't return it to the source. The dealership I called has three air intake boots, all without the nipple for the return line and are stuck with them. Another dealership didn't want to order because of the same reasoning - can't return if the part isn't right. What's interesting is that the boot has the right part number, but it's physically incorrect. Can anyone suggest a good supplier who can get the right part (both physically correct and right part number)?

Thanks for the heads up on that regarding the O2 sensor.

Yes, it's in California. I appreciate all the suggestions. The long way to work is a 60 mile one way trip and my knees and ankle will only let me work the clutch so long before they tire out (hence public transportation is my friend). I'll take it for a long run this weekend and see about burning all that 91 octane fuel. Should I be checking the O2 sensor? I noticed that back in 2004, it looks like the smog station checked my O2 sensor because it says I passed, but the one in 2006 shows NA for O2 sensor. Thanks for the suggestions and keep them coming.

My daily driver vehicle isn't passing smog. It's a 1978 Datsun 280Z. It only drives about 6 miles round trip when I do use it and sometimes I won't use it for 2 weeks straight. I've pasted the last three smog tests that were done to it. 03-27-04 - Vehicle Mileage: 270925 The vehicle didn't pass smog. It was due to a bad catalytic converter (it was the original one) so I should be happy it lasted this long. It was replaced. 04-07-04 - Vehicle Mileage: 270979 Vehicle has new catalytic converter and it passes with no problems. 06-09-04 - Vehicle Mileage: 273108 (2129 miles later) Vehicle doesn't pass smog this time. The only different between now and the previous one is the tank is full of 91 octane fuel (normally, I put 87 octane). This station is a different station from the previous two. The vehicle is fuel injected (if anyone is wondering). The vehicle was driven 20 minutes prior to showing up to the station and when I got there, I was instructed to drive right into the test bay, so I was tested immediately. Since my vehicle is so old, I can only go to smog test only centers and repairs need to be done somewhere else. Since I failed, I get one free re-test - so I need to try to track the problem down. My guess might be O2 sensor, but since the vehicle isn't driven far, it never gets a chance to warm up, so I could have carbon build up as well. Any other suggestions/clues/ideas would be appreciated. Below are three previous smog results. <img src="http://www.bimmerfest.com/forums/attachment.php?attachmentid=78027&d=1150137308">
