Thanks for all of the feedback. I purchased the car last year in April and had to acquire a lot of the vacuum lines under the plenum. (Thanks to this forum)
I don't know how old the filter is, but I believe it had been replaced while the plenum was off. I will check my paperwork from the dealer. The car now has 101,5XX miles on it. The injectors could be original or old, I don't know. When I got the car it had 97,XXX miles.
No SES lights or anything, just the sputter under acceleration, but again after a full tank, the problem seems to go away.
For now, the tank is full. I'm headed off to Woodward Ave. in Detroit for the annual Woodward Dream Cruise! If you should see a Bright Red '92 ZR-1 with the hood up, that will be me.
But the back up car will be the '07 Z06!
Let the games begin!
