I just changed my plug wires and man you can feel the difference right away!! I use to have the same problem at high RPMs of the car not wanting to run, but now DANG LOOK OUT!! Oh yea BTW my car only had 44000 miles on it
The best way to check if you wires are bad is to go to a very dark place, turn your car on, then see it there's blue archs jumping throughout your wires. If, so you're loosing spark juice through those archs
