Hello, hope someone can help. My cars engine lights came on and the car feels like it is in limp mode and has a misfire in cylinder 1. The car has 50k miles and just had the plugs and coils replaced 1200 miles ago. I'm at a loss after changing out the coil and plug with the problem remaining. The car is only driven once or twice a month, could it be time for walnut blasting?

 

Do you have a scan tool that reads live data?
