Smoging your 911
Hmmm as I look through my records at 90K miles and 100K miles the car passed inspection with flying colors. But now at 127K I dont know how bad the car could have gotten. Today I woke up, went to a final exam, got crapped on via exam, then went to the DMV on my lunch break (lucky me!) only to find out that I had to pay 150 dollars in registration fees AND get my car smoged. I'm scared but I dont know if I have any reason to be, sure my car smoke a little on start up and smell funny when you first start it but does this mean I'm going to fail? Maybe the PO used to detune the car before smog so it would pass? Some experience in this area would be helpful.

Guaranteed to Pass
Go to Kragen and buy a can of "Guaranteed to Pass". I don't know how it works but it WORKS! I had a water cooled VW that wouldn't pass even after I put a new cat on it. One can of G2P later......good to go. Supposedly it cleans out your combustion chambers. Run a can through your fuel tank then take it in for the test. Good luck.

Two suggestions:
1) Before you go through a lot of effort (seafoam, cans of G2P....etc) just try to pass the test.
2) Go for a very long highway drive right before, not only will it help burn some stuff away but you want that engine and cat as hot as possible when you get it tested.

My 1985 passed California smog at about 180K just over 1 year ago with original Cat.
I would certainly check the miles on the oxygen sensor. Mine is only rated for 60K miles.
I don't think there is anything to detune,< without reprogrammed chip>, fuel and spark advance are set. I would do plugs if you don't know the age and look at dist.cap/rotor visually.

What Matt said...just drive the heck out of it on the way to the test and make sure she's good and hot...can't hurt, and it's as good of an excuse as any

Glenncof: I read above I have new sparks, wires, filters, etc... all about 800-1000 miles ago. I'll do the "guaranteed to pass" formula just incase and drive the heck out of it before the test.

Perhaps we should ask you, "What makes you so unsure?"
Unless you have some wacky things done to your engine, it should be fine. My 78 passed with numbers well below allowed emissions of all gasses. Perhaps the hole-in-the-wall shop I went to was a bit shady. I don't think he's open any more. Although, I can assure you I didn't pay to pass, so to speak.

The only thing that concerns me is smoking on start up...which I know is common for 911s and isnt a big deal...but makes ya wonder..

Also now they check to see if the fuel system maintains pressure....new thing they check for. You might want to ask if its better to have the tank full of gas or empty to increase you chance of passing. I personally do not know if that makes a difference...but cheap to ask.

Whether or not the tech will do this test on your older 911 is up to his discretion. If the tech feels that the charcoal canister is too difficult to get to on a certain car he can exempt it from the evap test. Luckily our guy does so for most 911s . . . .
