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?
