Bucking and popping like a misfire and sounds like a misfire or the transmission feels like it's slipping and not going any faster??

Swap back to your stock wires and see if it does it, if not then you know it's a issue with the wires you bought. Or grab a scanner and watch cylinder misfires and see what one it is.

Im farely certain it is the wires, but why would this happen? Should'nt i just be able to plug n play?

New wires can always be bad, not much else to it.

The 10mm brand over the stock 7mm are just for looks anyway, they don't provide anything else.

likely a cracked plug

or you mixed up two wires. you can cross two and it will still run fairly well.

Sorry to bring this thread back to life, but what company were the wires from? I have had the same problem lately, 10mm wires from WBS causing a misfire in Cylinder 1. Was it a bad wire? Or did you just revert to stock again?

Doesn't matter on the brand, they can ALL do it; OE, aftermarket, cheap or expensive.
