I did a mail order tune from the Vette Doctors a couple years back. The car failed inspection again today and I'm out of ideas. I'm going to call the guys at New Era Performance here in Rochester on Monday and have them look at it and do a real tune at the same time. I guess I need "professional help". Thanks for all the suggestions.
We have had a few customers cars with that problem and theyhad to drive the car for at least 100 miles for all the sensors to reset. none were bad just had to be reset and some cars need more miles to get them reset.

If the code on the DIC is "current" will the sensors reset after 100 miles? Seems like the code would have to be cleared, run 100 miles and not reappear for that to work?
New Era can likely fix any issues with the tune, but you will need to drive the car and do several starts, etc. to get all the "Complete" status' required to pass emissions. Too bad you don't have access to something like Autotap, there is an emissions test function in it that will give you all the test "Complete"/"Incomplete" status' for all the various test.
Well, I guess I'll take off for a 100 mile trip this morning and come back and see if it'll pass! I want to get a tune at some point, but first I want to pass inspection before I get a ticket for it!!! What a pain....
Well, I went for a 120 mile trip this morning, stopped, shut the car down and restarted a few times and it still won't pass for the same reasons. I'm stumped.
Went out to the check the DIC for codes just now, fully expecting to have the P0153 again since at the inspection garage today it had the same "not ready" status again. There are no codes now either history or current other than an HVAC code. Do you suppose more miles would get it to the point where it would pass inspection?
Pretty sure that code is for the air pump. Are you still using yours. I think if you dont use the air pump, you have to tune it out or it will throw codes.
Update - the car passed inspection today. I took it to New Era for a dyno tune and Mike checked it out for me and told me that everything now was complete and it would pass inspection. But, he said that after he tunes it I'd have to drive it a couple hundred miles to get it to pass again, so I delayed the tune and went to the inspection place to get it passed as the deadline on the extension they gave me expired tomorrow! Now I have to find time to get back to New Era for that tune in the next couple weeks. At least now the pressure is off on the inspection!
Yes, I am! Next year I'll check for codes about a month ahead of when the inspection is due. That way I can clear them and get miles on the car so it doesn't get this close!!!

Just a quick note, someone had Autotap for sale in the parts section for $75. Autotap will tell you if you will pass inspection as it checks codes and ready status and sets up a nice little emissions screen.
Yes. For whatever reason I can clear the codes, drive it for a couple hundred miles and it passes. I'm kinda thinking that something happens as the car sits for 5 months without being touched during our NYS Winters that causes this. I never think of codes until it gets to be inspection time. That's why I say that next year I'll start looking for an clearing codes a month ahead and that'll give me enough miles to cure it before my inspection is due. Crazy stuff.
