Dean Morgan pounced to tap in Matt McClure's 70th-minute shot that had hit the post to earn Wycombe a point, moments after David McGurk had broken the deadlock for the Minstermen.
McGurk got the better of Kortney Hause at the back post following a Ryan Brobbel free-kick but it wasn't enough for York to earn a first win since the opening day of the season.
And, with another point secured as part of a now five-game unbeaten league run, Wycombe boss Ainsworth is feeling confident ahead of their next match at Rochdale.
"It wasn't a great game for the spectators but looking at the bigger picture we are unbeaten in six [in all competitions] and have 10 points from the last four," said Ainsworth.
"It's strange how we got those 10 points but it's 10 points. We will take the point, unbeaten is the positive, but we know we didn't create enough chances.
"It is still three wins and a draw and we believe we can go up to Rochdale next time out and win now.
"In years gone by we would have thought 'that's a tough game we are not going to get anything there' but not now.
"In the end there was only one team that was going to go on and score but York came for a point and got a point.
"They are not a bottom-two side and at the end of the season I believe we will look back on this and say 'York at home, that's not a bad point'."
