2005 CHEVROLET IMPALA

I have a 05 chevy impala with the mileage 91189 and I take care of my car very well. The check engine light came on and got scared and took it to autozone to check what it was. They told me it was a misfire from cylinder 2 and the spark plugs don't have numbers how they suppose to be set, so I decide to change all the spark plugs and wires all new. The code is PO302 number 2 cylinder misfire. The motor is 3.4 The motor kind of shakes when driving a high speed in the freeway like at 60 or 70. Transmission oil and motor oil was change recently. Is there any chance ya can help me?

Hello, I'm Danny.

It sounds like you are having an issue with the ignition coil for cylinder number two. I've attached the the replacement picture steps below for the ignition coil on your Impala. I've included a picture of cylinder number two coil location and circled in red. I've also included a picture of the part available at all AutoZone auto parts locations. Hope this helps and thanks for using 2CarPros.
