It sputters right from the beginning. I threw a cylinder 6 misfire check engine code. Has no power. When I changed the spark plugs i saw cylinder 6 plugs we fowled black while all the other plugs we coca brown. I also noticed the #6 injector was fouled when i changed the new one. I will check for a chipmunk nest in the exhaust to see what happens. I will vacuum out with a shop vac. Thanks
