Air your tires up to high hell, skinny street tires that are the proper size helps too. Beat the shit out of it before smogging, a hard run right before testing helps. When you go to the smog station have your buddy sit in the truck and keep the rpms above idle until the tech comes out to get your truck. Those are a few things I know other than the obvious stuff
That sucks that your HC and NOX are high... when you lower one the other generally goes up, you are running out of wiggle room.
This Star station shit is really pissing me off...
I believe there are some shops that have a smog exemption plan that is good for 2 years. CASH only I think... :)
Marc: I believe you are entitled by law to have a smog run done without a failure counting against your vehicle. It's called a pre-test. See here:
Note a place doing a pre-test may charge you as much as an actual test. That said, I asked a smog place about a pre-test when I had just got my 720 (PO didn't smog it; I was aware when I bought it), and they hooked me up with a partial for free. Maybe just feel around, or if not, pre-test costs less than failing and ending up in the gross polluter bucket.
Also, this looks like a really good reference for Cali smog:
That said, I know an _awesome_ shop that specialized in Datsuns, but they're up here in NorCal.
Let me know if you have other questions. Cali folks have to stick together.
if the vehicle is "star test only" even the pre-test is recorded.... so I have been told
Steve: I've heard the same thing. What the smog guy told me is that they transmit it either way, but if you fail during a pre-test, it doesn't go on the vehicle's record. Of course, given that they have it, they could turn around N years down the road and say "hey, actually, we're going to pay attention to these now."
That said, for the immediate term, if Marc doesn't have any other options, the pre-test is still a good option. Especially if the tech cuts it off before the test actually completes (but if doing so, I believe the machine doesn't give a printout)
SUCK IT CALIFORNIA!!!

Still on the original carb and catalytic converter. BLOW ME CALIFORNIA!
It turns out the truck was actually running too lean 2 years ago. I riched up the idle mix screw a bit and crossed my fingers. Changed the EGR valve, the truck runs like a bat out of hell, but still shakes a bit at idle. I'll let it shake.
Woah, those are some serious numbers. Good work.
this brings a tear to my eye... so beautiful
