Brett Pitman reminded his old boss Eddie Howe of his scoring ability as Burnley's play-off hopes suffered another blow, much to the delight of Bristol City manager Keith Millen.
The striker, sold to Bristol by Howe last summer while he was still in charge at Bournemouth, opened the scoring three minutes before the break with an unstoppable finish from Albert Adomah's right-wing cross.
It was an all too familiar sight for Clarets boss Howe, who admitted: "Brett is the last man you want to see receive the ball in that sort of position as an opposing manager.
"I have seen him score goals like that many times. I never wanted to sell him at Bournemouth and I'm sure he will go on to be an even bigger force in the Championship."
Howe had few complaints about the result, as he said: "We were better than in our previous match, but still disappointing at both ends of the pitch.
"I thought we controlled possession for long periods in the second half, but didn't create much.
"It's an understatement to say that this is a bad time in the season to be dropping points and one from a possible nine is not good enough. We need to work hard during the international break, which may well have come at a good time for us."
It was City's fifth win in six games and manager Millen said: "It was a complete performance from the team. Everyone worked hard and we thoroughly deserved the points.
"It was important that we bounced back quickly after defeat at Norwich and I freshened the side up with a few changes."
