I've just got this car and after a week driving it the check eng. light comes on, so i go to AZ and they toldme it's the coil pack. I've replaced it and it came back. Went back and the same code with another one came out Misfire#2 and sys lean bank1. he told me that the wire's my also needed to be change, I changed them and a fuel filter for the leanness. Well it came back a third time. this happen after I change the spark plugs when I bought the car. Needed help!!!!!
