Wycombe, meanwhile, could name only five substitutes on the bench, and fell behind early on when Howson's effort found the bottom left corner.
The Chairboys refused to wilt though, hitting the woodwork twice in quick succession through Pittman and Scott Davies.
Leeds' Bradley Johnson did have a header cleared off the line but Leeds struggled to repeat the fluency they showed at Old Trafford and Wycombe equalised in the 63rd minute when Davies' long pass to Pittman allowed the striker to cut in from the left and fire past Casper Ankergren.
Leeds United manager Simon Grayson told BBC Radio Leeds:
"Obviously we are disappointed not to win the game. One week you can beat one of the best teams in the world and you're on a high, the next week you are disappointed you haven't won at home.
"But credit to Wycombe because they played very well but we were below the standards we normally set. But who knows, this point could prove to be crucial at the end of the season.
"I think there are many reasons we didn't play well today, but I'm sure people will say it's a case of 'after the lord mayor's show'.
"The players know they haven't played well today but you can't be at your best every game and least we took a point."
Wycombe manager Gary Waddock told BBC Three Counties Radio:
"The players were excellent today. Conceding an early goal at a top-of-the-table side, you think it could be one of those days, but the players responded.
"I thought it was a confident, extremely accomplished performance.
"We defended well today. We looked solid at the back and through the middle of the park. There were some excellent performances in there."
