I have been away from my car for a week but when i came back i had some stuff that came in. So i put on magnecore spark plug wires and a Bonez air pump filter. However, i took the car out and now when im around 7000 it seems like it hits a brick wall and lose power. I didn't think anything i did would have that effect so could it be the 5th/6th ports are shutting? Anyone have a similar problem?

could be... but why would they, unless your new wires are less shielded than the old ones and are causing electrical interferance with the 5th and 6th port solenoids at a certain spark firing rate. try it with the old wires and see if it still does it.

it might just be the wires....
