sounds like a tight spot in the chain

Think a good clean and lube should solve the problem?

can't hurt but if there's a tight spot then probably not. you can free a tight spot using two pliers by twisting the stiff link back and forth until it frees up but its a bit of a bodge and a lot of people just replace the chain if they find a tight spot because of the risk of it snapping. if i was you i'd inspect all of the links individually and check to see if they all rotate nice and freely.
