    You can go to Autozone and buy two new coils,and try them,if it doesn't solve the problem,then take them back and tell them,it was something else and they will refund your money back.What does your spark plugs look like?

  • Joe Russell Apr 28, 2017

    no i havn't check the fuse will a fuse cause yellow fire from the coil and ignition wires and black smoke coming from tail pipe?

  • Joe Russell Apr 29, 2017

    i check the video out my ECU have a little toggle switch with ON/OFF for me to pull the codes how do i operated the toggle switch?
