Hi,
I'm quiet new owner of 1990 Zr-1 corvette and I just decided to pull off the plenum due to first injectors change after 28 years
My question to more experience members is do I have to change coils on 50k miles car or not. Dont know if current oem products are as good as factory coils.
Thanks for some advice
Btw Car run ok on normal power even on high rpm, just on full power mode lose power and hesitate to accelerate
