Posh get them back with interest after losing 0-2 to a poor Wolves side at London Road in September:
Peterborough moved off the foot of the Championship with an emphatic win over Wolves at Molineux. 
Darren Ferguson's side withstood early pressure from the hosts before Lee Tomlin struck to take the lead.
Tommy Rowe doubled the advantage two minutes before half-time, while Dwight Gayle wrapped things up with the third after 69 minutes.
Peterborough's third consecutive win sees them move above Barnsley and Bristol City.
Wolves tried to make home advantage count early on, with Roger Johnson denied at a corner by a smart save from Peterborough goalkeeper Robert Olejnik.
The visitors held firm before going ahead in the 17th minute, Tomlin pouncing from close range when Wolves failed to deal with a Joe Newell cross.
George Boyd put a chance to double the lead just three minutes later a long way over the bar, while Olejnik blocked a chance that fell to Wolves's Kevin Doyle six yards out.
Doyle twice came close to equalising before Peterborough went further ahead on 43 minutes, Rowe firing the ball home from 20 yards.
Jermaine Pennant came close to pulling one back for the hosts after half-time, but Gayle put Peterborough within touching distance of victory when he met Mark Little's cross with 69 minutes gone.
It was the striker's sixth goal in seven appearances since moving to London Road from Dagenham and Redbridge on loan, a deal that will be made permanent in early January.
Wolves manager Stale Solbakken: "Rather than pointing fingers at the players I will take the blame myself.
"Sometimes when one, two or three players have an off day you can explain it. But I think I saw seven, eight or nine players have a really bad day with the ball.
"Defensively we were vulnerable to counter-attacks and I didn't see any belief after it was 2-0."
Peterborough manager Darren Ferguson: "I played here at Wolves for five years and I know what the place is like, not many teams come here and win 3-0.
"The two key moments were the second goal before half-time and getting the third which killed the game off and then we saw it out quite comfortably.
"Now this consistency has to remain for us to get out of trouble."
