    • Found the fuel trims to be a bit high negative. Meaning system is running rich. Found the Computer showed the fuel alcohol content at 19%. Without ever adding E85 fuel to the vehicle that is not possible. Erroneous High alcohol content readings can cause these fuel trim issues. Computer is still showing the odd misfire even after resetting everything. But too few to pin it down. I would recommend trying it for a while and see if the misfires get worse.
    • Valve cover gaskets are not leaking at this time.
    • Did not experience or see any reason for a burning smell.
