Fellow ///M guys, my check engine showed up and I did get my coder and got the codes.. It's P2247, P0304 and P0050.. It said I'm having a miss fire (p0304)and some temp issue with the code (P0050). Not sure about the p2247..
If I'm changing the spark plugs co my mileage is 77k miles already should I also change the coil packs? Thank you guys
