Thanks for the info. I don't have an EGR system though. I'm about 95% sure it's my o2 sensor, as I usually get a CEL for it on long trips. I run 20 oz of water through my engine every so often, so I don't think it's carbon buildup.

The Camry passed today, but idle HC emissions were way high, and the CO were way low. Could've been because the car was parked for 10 min, and took a bit to get out of open loop.

We don't need emissions checks in Florida, though I'm going to start getting them done eventually to see what I can do to reduce emissions.

Hello -

Here's the result from my Saturday test :

Attachment 823

The car was running stock for the test.

I do have to go back because I reset the ECU/PCM on Friday for one of my tests. The (OBDII?) ECU/PCM needs to run for awhile before you get the smog test. This is almost better, because I can see if the emissions change after the ECU/PCM has been "run in" a bit.

Hello -

I just did a follow-up smog test after letting the ECU/PCM settle in :

Attachment 839

My car passed with even better numbers for HC and CO pollution (below the average !), but the NO went up. I did have the HAI online after the first test and for this test, so maybe this is an effect of the (mild) lean-burn. I didn't have the ScanGauge online, but I would guess at least 130+ degrees F HAI.

To settle in the ECU/PCM, I did gentle driving but nothing that would risk throwing a code like EOC.

Toyota and Saab

I had a Toyota 4Runner. I tested it with with and without a CAI. With the CAI, emissions were about 1/3 of stock set up. I experienced the same (although less dramatic) with one of my Saab 9-5s. I wish I had the numbers to post.

Yeah, I wish I had my previous smog test output from a few years back.

What I realllllllllllllly want is a way to measure emissions on the fly (for under $50 ). It would be interesting (for me) to know my real CO2 lbs emissions. If nothing else, I want to know my NOx output, because that's the catch-22 of lean-burn.

Well if you're not doing something to attempt to lower you NOx while at the same AFR then you could get an AFR sensor and guestimate based on amount of leanness.

It's interesting the comparison of your two test sheets, the drop in the other number and increase in NOx shows that the ECU really leaned out.

I have a digital AFR that I need to post a thread on. Will do so by tomorrow ...

Yeah, I think that I "trained" the ECU/PCM by driving gentle after the reset. One thing I have noticed via the digital AFR gauge is that the car almost *never* goes rich. It almost always goes from 14.7 or leaner, period.

PS - You don't have to disconnect the battery to reset the Saturn ECU/PCM. There is a (must be always-hot) fuse called "PCM B" in the engine compartment fusebox that can be pulled to reset the ECU/PCM memory.
