Emissions Testing
 

Each state has their own way of measuring emissions.
In the state of Oregon one of the nice rules was that when
your car reached 20yrs old they no longer measured emissions.
That was very nice for my 73 LS6 because I had to put all the
air injection crap on it every 2yrs.

Anyway, I've just taken the ZR-1 down for testing here in
Washington and they no longer put the car up on rollers
for the test and they no longer inspect the gas cap !!!
Just a run up to 2500rpm for about 5seconds and that's it.
The PASS slip no longer shows levels of gases either.
Not sure if the FAIL slip does.

In a time when I see and hear that other states are stiffening up on
emissions it's good to live in a state that seems to be lightening up.

I am curious about how many states still use the rollers when doing emissions testing.

Hi Scott, yes I experienced the same change in testing procedures that NYS/DMV applied to cars in high density areas. It seems that two years ago the roller test was abandoned in favor of a short, fixed rpm test with an exhaust gas analyzer and a data link using the ALDL. Even the results of the analyzer are left off in favor of a "pass/fail" statement. The roller was not a state wide procedure, it was only in high density areas that actual tail pipe emissions through out a "simulated driving loop" were measured. There was a bit of 'raising the bar' with the emissions levels that they would call "passing" on older OBDI cars. It wasn't as bad a creep as CA is using, but I was beginning to think where will they stop. NYS/DMV Antique status is 25 yrs, and they have not decided to include OBDI cars in the same group as pre-OBDI cars that have an exemption from emissions testing in high density areas. I was always proud of my OBDI LT5 passing the testing even if it was shooting at a moving target.

I miss the actual gas content results. I used to use them as a "window" of sorts to what was going on inside the combustion chambers.

No testing whatsoever here in Florida.

In Maryland you can put Historic plates on your car when it is 20 years old. No emissions or state safety inspection is required with Historic plates.

Scott, last time I checked the Oregon 20yr old rule only applied to cars up to 1975 - so basically anything built after 1975 still had to pass emissions. Has this changed? Would be great if it has.

Re: Emissions Testing
 

Ya know, I actually don't know where they are with that now. I lost interest in that along with the Ducks and Beavers in favor or the Huskies and the Cougars a decade ago :)
I do know my 73 did not have to go in anymore.
PS I decided to go with "Neighborhood Watch" for my new router name.
That should get some attention.

Ditto for South Carolina...

Re: Emissions Testing
 

In NH as long as the "check engine" light isn't on, you pass. They figure the car is doing it's own testing continually. Makes sence to me.

Re: Emissions Testing
 

I never got to find out, as my 1991 ZR-1 is registered in MD as an Historic vehicle, and is thus exempt from safety and emissions inspections.

No testing at all in Michigan
