tuned port fuel injection
 

I have heard that the tuned port fuel injection systems on the 85-90 corvettes (i am not positive when they stopped using the tuned port fuel injection) are very costly and unreliable. Should i lean more toward buying a 90 corvette instead of the 80's? What year did they stop using the tuned port fuel injection?

thanks

i thought that the crossfire injection was the problematic system?
