I have testing coming up in March. I was dyno'd last year so I think I wouldn't need it again until 2004. But I heard that they are only doing plug ins now. Is this true?

I've heard they are doing plug in's on 96 and newer cars.My sticker is up in 2 months so I'm just throwing my Cats on and give it a wirl

 

As long as you still have the same plates as last year, you won't be redyno'd. Any time you change plate numbers the system will require a new full emissions inspection on the first inspection.
96 and up go thru the OBD II hook up. As long as you did not disconnect the bat just before nor cleared dtc codes that will be all that is needed. If either was just done, the computer will detect this an require a full dyno run. Good idea to put cats on for your inspection, we are also required to check for their presence and fail if they aren't there.

 

Hey MOD313, I lived in Marshfield for 26 years,just moved out 2 years ago. Small world

 

Hey Mod313, do you guys check to make sure the cats are in the stock location?

 

I run longtubes,so the Cats are located farther back then normal.My last inspection they noticed it,but said nothing.

 

Thanks for the info.

thanks Slowhawk. I'm worried about the single turbo I'm putting in. It obviously moves the cats, and has no EO#. I think I'll just wait till march, get the car inspected with the stock engine, and then put the new motor and turbo in.

 

What about 1995 vehicles? I had my Z dynoed for emissions 2 years ago, safety last year. What about this year? How will they test emissions?

 

Emissions are every other year unless, as I said, you get new plates. 84-95 cars/trucks go thru the full dyno test while 96 & up go thru OBDII hookup. As long as everything that test looks for passes, no dyno test will be required; if not the full test is called for.

 

From what the inspection guy told me last year, I was under the impression that 96+ was ODB test only. If you fail the plug in, you can't just hop on the dyno.

Reason I say this, is I went last year with an ODB1 PCM in the car Of course it failed the plug in test, but I passed with flying colors on the dyno. He said I'd fail this year, becasue the PCM test is mandatory.

 

No, not passing the plug in won't necessarily fail you. On those cars/trucks that don't pass the plug in (quick pass) will then be put thru either the dyno or two speed idle test. If that test fails you then get the rejection sticker.
Now I won't ask how an OBD II car has an OBD I connector, lol.

 

What happens if you fail twice when trying the emissions? Is there a limit where they will finally pass you?

 

RealQuick,

It goes something like this. If you make an honest attempt at getting the problem fixed, by spending a certain dollar amount, and you are still failing (depending how badly) you can file for an exemption. That's how I understood it a few years ago, although I don't know of anyone who applied for an exemption.
