Under full power, the car shudders and there is no performance difference.

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.

Ive got a guy here in Bancroft (1hr away from Peterborough) that I trust to work on my ZR1 and going to use to help me re and re the plenum and install the injectors and coils. He is a perfectionist but not familiar with the lt-5. I think between this website for guidance and trouble shooting, and a skilled perfectionist like himself that I can use to help me do the install, we should be fine. Ill let you know how we make out with mine and if you want I can give you his number....he could come to Peterborough and give you a hand in your garage.

Also, in my travels i noted a Corvette specialty garage on the 401 somewhere between Oakville and cambridge...not sure where exactly but it was called Grand Sport Corvettes. Might be worth giving them a call and asking if they do service on lt5's.
