ok I poor this stuff call Pennzoil Fuel in my gas tank then filled it up with gas to clean my gas tank out. then the next day it sounded like it was in N when u put the gas down the noise like that but the speed went up. then after it stoped now its doneing it again and im still on the tank of gas that i put the stuff in. Would it be making that noise because its getting clean or what could it be
