90 wont pass smog - ZR-1 Net Registry Forums

Tom;

The previous owner brought the car to Taylor Motors for the SMOG. That's when theproblems started. Yup, I think I know the guy from Lithia, Mike Brooks. He did a lot of work for me on my Z06, knows his stuff. He is now an airline pilot. Quit about three years ago.
But here is the latest news. The good first, I took the car over to a friends shop, put it on the scanner and as you mentioned, the 02 sensor on thre right bank bad. The dealer did not run a scan, but was sure anxious to remove the intake again claiming a leaky injector. I pulled the plugs and they all looked great.
Also, and the dealer had the intake off to replace three injectors, their is a small rubber manifold, 4- holes, two in two out, that is located just under the throttle body area. When the tech put this back on it was on backwards, two holes on one side are smaller than the opposite side so a massive vacum leak. New 02 sensor and vacum leak fixed and wala, idle is normal and at 2500rpm it holds without variation.
Now thw bad, When the dealer removed the vacum tube, left side and two torx bolts hol it in place and it crosses or lays under the small 90 degree intake collant purge tube, they cracked that purge tube where it press into the intake. Found this when I went to move the rubber hose up a little, just touch it and collant leak. So I had to jury rig a fix to get it home. Now I am on the hunt for the 90 deg. tube.

I am taking it in to a friend tomorrow for a SMOG, so I hope this is the final chapter in the story.

Again, thank you all for the help and I hope this site does not change, it is great.
