I used an OBD2 reader to read the readiness monitors.

 

Misfires caused by?

This is a low mileage car. Garage kept, safe warm and dry. Could wires or plugs be bad already? 21k right now 13k last July when I bought it.

 

Low mileage guarantees NOTHING-misfires can come from many places, plug, wires, coil(s), injectors.....

 

DO NOT HIT THE RESET BUTTON ON YOUR CODES !
You will have to do the entire driving cycle again.

Been there and done that....

Just when you think you know everything. This is new to me (filed away for future use). Thanks Toque.

 

No prob....
I had my battery disconnected this spring, and had to drive the OBII driving cycle before my safety inspection. I did it 2x on 2 different times. I filled up after each short drive. I was measuring my heights for my suspension at the same time and wanted to keep a full tank so that my measurements would not be thrown off with the lower tank of gas (yes it makes a difference in height). I failed for EVAP and the emissions guy told me to run it to 1/2 tank, and I will pass..... he was right...

Is this regardless of what code was actually cleared? I hit the reset for the AC code but had no others. Does that cause a complete do-over? If so, that explains a lot.

 

I own a Actron CP9135. Purchased it maybe 5 or so years ago. I have to tell everyone here it was money well spent. I know whether any of my later model cars will pass inspection even before I go to N.J. inspection having this unit. Most recently had a problem with my wifes car not a C-5. Check engine light has been on for months but the car ran great. Well this month of August is inspection month for her car being we have inspections every 2 years here. The Actron showed 2 codes that both had to do with the Evap System. One code showed a low leak and the other a large leak in the system. The small leak was a bad gas cap and the large leak was a defective Evap pump mounted to one side of the gas tank on her Dodge Intrepid. Replaced both and passed inspection Monday afternoon after putting maybe 50 miles on it over this weekend. The Actron CP9135 shows you the codes picked up in the system. Can Erase the codes so check engine light goes out and will show you all of the monitors. I used the Actron after changing out the cap and Evap pump checking just about every 10 miles driven and watched on screen as it scanned each monitor showing which ones were ready. The Evap system monitor took the longest to become ready so that I could bring the car in for inspection. From what I understand N.J. will still pass your car if one monitor is not ready as long as all the others are. My Actron actually will show the word Pass if it reads that your car will pass inspection. Payed a little over a hundred dollars for the CP9135. Worth every penny I feel. Since I have had it I don't ever feel like I am in the dark anymore when it comes to any of my late model cars when there is a problem.

 

Isn't that what I said?

 

I have one and a PC program for my laptop that does much more. Between these 2 devices and what's built in to the Vette, I can track down most issues quickly.

 

I believe it does yes.

A long time ago shortly after I had my heads/cam installed I threw a lean code on my way to get inspected. I reset the codes on the DIC. The inspection guy told me that everything was "NOT READY". I went back to LG's and they fixed the lean issue code (had something to do with the Vararam taking in too much air, and the O2 sensor misreading it), and I drove the OBII driving cycle a few times. I went back and passed testing.

I recently went through the same problem you are having. The exact same "not ready"codes came up during inspection (because I disconnected the battery). I drove my car about 150 miles and went back to inspection 4 times! It still did not pass. When it was finally ready, my CEL flashed on and I had lean codes from a recent header install. That's when I knew it was "ready"for inspection, but still wouldn't pass due to the new codes. I then needed to get a tune.

The main thing to consider is that every car is different and you need to keep driving it until everything resets. It will eventually be ready. I wouldn't, however, keep rushing back to inspection. It's a waste of time.

 

Why the heck are you down shifting an automatic? Begging for trans problems?

 

Please explain...I really do want to hear this one

 

I don't think it was a stupid question (smartass).

I was wanting to understand the impact of a HVAC code on emissions testing. If there was a connection with ALL tested components and the "reset" it would "seem" every freakin reading at the station would have said NOT READY as opposed to only three.

 

The HVAC has NOTHING to do with it, the entire system is reset when you clear any one code, some of the I/M tests will run quickly and pass others won't after the reset (smartass).

 

Took it back today and it passed. over 200 miles since the first attempt and I still had one "not ready". EVAP only, but one "not ready" will still pass. So now I have AC that works correctly, no CEL, and I am legal...think I'll go for a drive !!!

 

WOW! So much craziness! Someone needs to invent a "Pass Chip" that plugs in somewhere and tells the inspectors everything is OK.

 

And that would be the 1st thing they would look for.
