Leicester City captain Stephen Clements missed out with a calf injury with 18-year-old youth academy product Andy King stepping in for his debut.
Wolves again started with £1.5million summer signing Freddy Eastwood on the bench.
City carved out the first chance of the game on eight minutes with Matt Fryatt controlling a Radostin Kishishev knockdown before firing over from 12 yards.
Wolves hit back with a Carl Henry drive which was beaten away by Marton Fulop.
Leicester threatened again on 13 minutes with Patrick Kisnorbo heading Joe Mattock's corner narrowly wide.
A slow-paced game had to wait until the 26th minute for its next meaningful attempt on goal with the Wolves keeper grateful to see Mattock's 25-yard drive dip just over.
On the half hour mark, Fulop came to City's rescue when he raced from his line to block a shot from Stephen Elliott.
Wolves threatened again on 41 minutes when Michael Kightly whipped in a low cross with Elliott slipping before he was able to apply the finishing touch.
Two minutes after the re-start Fryatt almost broke the deadlock with an 18-yard drive which had Wayne Hennessey at full stretch.
City continued to press but without making much impression on a resolute Wolves rearguard.
With the visitors failing to fire upfront, manager Mick McCarthy made his first change in the 66th minute with Eastwood replacing Elliott.
The Foxes made their first practical switch on 73 minutes with Kishishev making way for Carl Cort and Iain Hume dropping into midfield.
And Cort almost made his former club suffer on 78 minutes when he shot into the side-netting after seizing on a rare defensive error.
Kightly twice tested Fulop in as many minutes, before City substitute DJ Campbell headed a Hume free-kick straight at the keeper, which was the last meaningful goal threat of a poor match.
