But, as Adams later suggested: "so much for preparation''.
Dele Adebola's 48th-minute strike pushed Coventry up to ninth in the table and ended a run of three consecutive wins for QPR.
With only a point separating the sides in the table before kick-off this had the makings of a close contest but both sides were on a high, heading into the match on the back of victories.
Yet QPR appeared to be undone by the expectations of the home crowd after their victory last week at Cardiff City and it was Coventry that dominated for much of the first half.
In the 17th minute Adebola was the provider, setting-up Colin Cameron, who woefully scuffed his effort well wide of the target.
Coventry continued to keep up the pressure on the QPR goal, but towards the end of the half Rangers finally sparked into life.
Zesh Rehman went desperately close with a header in the 42nd minute and soon after that Lee Cook completely lost his marker, bursting into the penalty area to deliver a low, hard, drive that was superbly pushed away by keeper Andy Marshall.
But the second half followed the pattern of the first with Coventry dictating the play. Leon McKenzie squandered a great chance to put the visitors in front, blasting an effort wide with just the keeper to beat.
But just two minutes later Adebola grabbed the only goal of the contest, comfortably shaking off his marker, Rehman, before running into the QPR area and firing a powerful shot past Simon Royce.
Just after that strike QPR forward Marc Nygaard had a header that landed on top of the crossbar while both Cook and Jimmy Smith continued to keep the Coventry defence on their toes.
Even so, the Sky Blues will feel they were just about good enough value for the victory and they nearly grabbed a second late on with McKenzie's header, from all of three yards out, flashing narrowly wide of the post.
