Engine Moan and Exhaust Smell in Cab
I have been having a strange engine moan now for a few weeks. It happens on light acceleration before the truck shifts at all speeds. It can be faint or extremely loud and I can keep it doing it if I keep the throttle in the same spot when it starts. Also now lately when it does it I can smell exhaust in the cab. What do you think is wrong? No codes are being thrown...naturally

I had a fuel smell in the cab. The truck was running good but felt down on power. Tracked it down to a loose spark plug. I didn't have any codes either.
The truck had a 100k on it so I changed them all while I was in there. Runs great now and no more gas smell.
