WINNER WINNER. It was the tune.. The shop that repaired the electrical problem also “adjusted” some things in the tune. This was the problem. Before it was in closed loop and worked fine, he put it in open loop all the time and that’s where I had the issues, downloaded a new tune in closed loop and NO Problems.. I have a lot of dialing it in, but it’s good to go now.
I had a similar cam in my C5 5.7 with no issues. I think that messing with the tune after the wires where fixed maybe has something to do with this issue. After replacement of the wires the car needed to be run with you in it to make sure that there wasn't any more persistent issues steming from the short.
After that then the tune should have been left alone if you had non issies before. I don't know about turning I'm not a tuner am a wrench turner and a schematic guy. Maybe you should get an independent tuner with a good track record in your own area to take a look at the tune. If you have the same guy whonwrote your tune taking a look at the tune you have he will say everything is perfect.

yes sir! You were correct. Shop changed my tune from closed to open loop. Got a new tune back to closed loop and it’s running ****. Still have a lot of dialing it in but it’s not cutting out anymore and that’s what I wanted. Thanks for your help
Thanks for the update.
As you mentioned, if your car has issues in open loop, your tune, especially fuel
trims are way off. Dial in VE and MAF tables as a starting point.

Jace,
99 T/A's had a gauge cluster recall/TSB back in ~2001 or 2002. Probably around the time your car went into storage. Might be worth checking to see if that applied to your VIN.
My 99 T/A was affected by it and dealer covered replacement. The gauge cluster did some strange things like gauge sweep on start up when it started to malfunction. No idea how the malfunctions progressed beyond that. The cluster was OK until it wasn't. I don't think GM would have replaced mine if a random sweep on start up was the only issue.
I don't recall if Camaro’s were also affected.
