Hot Cam emissions update....

I just got back from the emissions testing here in Rutherford County. After 1,000 miles since cam installation into my corsa equipped, stock programming 96 LT4, I am happy to report passed with flying colors. No codes, no leaks and no backfiring. Here, they plug up the computer at the OBD2 jack.

As I got back in to drive off, the kid said, "I sure like the sound of those cars!"
I just smiled and drove off.......... :party:

IBEAM700, they don't post numbers such as HC's and such...It simply says 'OBD inspection: result-pass.

Now, the maximum allowable here are: HC ppm/220, CO%/1.20

Hope this helps. :)

If memory serves those are the same numbers Ca. uses on their smog test. It’s kinda a bummer they don’t provide the actual numbers for the emission testing.
How are you supposed to know what part of the emissions system needs attentions if you don’t have the numbers? Guess that’s just the government at work.

Thanx for the info. :cheers:

In theory, this is what the OBDII system is designed to do. It runs self-tests on the car to check operation of the emissions control systems and stores codes if anything is amiss. Yes, you could be dumping raw gas out of the exhaust and still pass as long as the computer says everything is fine though you're OK. This is also the reason why us 96+ folks have to use resistors and other tricks to disable things coughCAGScough. Otherwise the PCM will set/store a code.

One additional note: If you clear the codes immediately before doing the test they'll sned you away to come back later and try again - the computer needs to complete a "drive cycle" before giving the all clear.

:iagree: They're just starting to phase in the OBD II test in St. Louis. Before the car had to go on a treadmill and they "drove" the car (another horror story in itself!) through a representative drive cycle. Starting this year, they plug in to the diagnostic connector. As long as all the OBD II self-tests are completed by the PCM and there are no codes stored, the car will pass.

Re: Hot Cam emissions update.... (96GS#007)

I'm in VA and they use the treadmill, but I'm sure its still an OBDII test. Just had mine done a few weeks ago. Testing took like 45 minutes or longer. They ran a series of tests with the connector, then he drove the car on the treadmill to different specified speeds (think this was part of the sniffer test) while the computer tracked it.
