I have it going in this Monday for service, but I am not confident my garage has worked on a ZR1 before. What does anyone think the repair price for the injectors may run me? Does anyone have reservations about bringing a ZR1 to any garage? I am near the Peterborough area and am unaware of Corvette service shops in the area.
Thanks for the input.

Sounds like the same problem I had with my 1990 until I installed a set of new injectors.
FWIW, I wouldn't trust any non-GM dealer with a 1990 ZR1 (except the few specialists discussed by registry members). Likewise, there are very few GM dealers I would trust.
I recommend you check the injectors when the engine is hot to verify low resistance. Do the work yourself, there are a number of resources in the technical section.
Good luck
