I just got done doing the intake gaskets on my buddy's 99 Tahoe and when I put the distributor back in I was off a tooth. I got it back in and running but when I went to set the timing I couldn't because there was no timing plate with the marks on it that attaches to the timing cover? I don't know if it rotted and fell off or what the hell happened? The check engine light is on now because the timing is off and I need to get this thing fixed so I can get it back to him tomorrow. Thanks in advance guys!
no timing marks?

96 and later are listed as "non adjustable", as far as timing goes. I would hope that they still have the marks.
I would think that with a cam sensor and a crank sensor, it would find itself.
I wonder what happens if the cam itself is physically off a tooth or two, from where it was? I don't use OBD2, so we need someone else to chime in here.
How to identify if the distributor gears are in the right configuration.

Did you mark the position of the rotor in relation to the bottom of the distributor? If you didn't and the rotor got turned while it was out, that would be hard to find the right position. There should be a timing mark on the cover, but you would probably have to remove a lot of crap to find it.

If you know you dropped it in 'off a tooth' stop posting on the internet and get out there and fix it. I'm pretty sure it has to be dropped n at 0, the computer handles all the advance and retard.

I think you mean the distributor housing. The bottom of the distributor is the gear and that's fixed to the top that houses the rotor.
