Engine miss with power key on - ZR-1 Net Registry Forums

Your mechanic is probably right. With that mileage those secondary injectors probably rarely got used. This is a very common problem even at that mileage. Have all the injectors (primary and secondary) replaced otherwise you'll be doing this over and over again. Also make sure you do not replace them with original injectors from GM, their design is prone to this failure. RC's or Accels are recommended. For that matter Jeff is recommended....

FWIW, I'm doing mine this week for the exact same problem. I'm putting accels in.

Good luck,
Hans
