Make sure all the wires are snapped into the coils, then make sure all the coils are bolted down snug.

Check Plug, maybe fouled?
Read Code....
Switch coil packs see if motor changes while running.

What are u talking about lol? That would do the exact same thing if not worse, u do not rearrange coil packs, where it's at is where it goes, ALWAYS...

I will be replacing the spark plug wires anyone know if its simple or a diy

ttaylor993

Yeah, it's a DIY. Althoug, you will have to take the throttle body off. Also, expect to crack the wiring harness if it's a high mileage car. They get brittle with age.

yes do you have a link the mechanic said the wiring harness is very brittle and the wires are all messed up

ttaylor993

I didn't worry about the wiring harness. But, I did get new connectors for the wires to the coil packs and new plug wires. I paid $16 for a set of 6 connectors, although I only needed 3. Got them from eBay. I don't know when your plugs were changed but if you're gonna change the wires you may as well change the plugs. And if you gonna change the plugs, be sure to clean the plug valley BEFORE you remove the plugs. You don't want any of those bits of plastic from the harness and connectors to fall into your cylinders.
