So we were driving normal 60mph and all of a sudden the murano starts missing when you press the accelerator and check engine lights starts flashing than stays on. Stop and had codes read and showed multiple cylinder misfire. Changed all the plugs and front 3 coil packs, changing the rest change this weekend on the back side when manual comes in . Has anyone had this issue currently cant go more than 25mph and light went off when spark plugs were change by itself. Pleas help and share trying to see what the problem is .
