Hats off to ya! That problem rises above "the norm", far as troubleshooting goes! Now get ready for some permagrin!
Jim, are any of your other Zs modded, or is this your first P&P (or whatever)? Boy, I remember my first outing after I P&P'ed my top end. It was a totally different, TOTALLY different animal!!
And, just for some icing on the cake, I was on my way home from that first test drive when a red Pontiac (LT1 Firehawk?) with a couple a young "hotties" came up on my tail. I was doing about 60 when they pulled out and passed me, hesitating along side long enough to smile and wave before nailing it and completing their "pass".
I don't know who they thought I was, or maybe didn't care(?), and if it had been some young guy(s) instead, I probably would have ignored them, as I usually do. But! A couple hotties in their 20s? That never happens (to me) -
more that once or twice a day, anyway
They were definitely teasing, and I was suddenly transformed to a teenager in the Corvette I could never afford when I was a teen -
game on!
We played "leap frog" a couple times before I turned the LT5 loose to cap it all off.
Man, whata rush!! But, to be honest, I don't know if it was the "new" LT5 or the flattery of a couple gals wanting to play with this ol phardt and his Vette. Doesn't matter. I put it in the "good times in the Z" memory file, and always grin when I replay it in my mind!
Good hunting, Jim!
