Jordan James' goal earned Leicester their first win in six games
Jordan James scored a stoppage-time winner for Leicester to dramatically deny Norwich their first point at home and pile more pressure on Canaries boss Liam Manning.
Mathias Kvistgaarden had put the lowly hosts ahead in the 62nd minute, pouncing on some poor defensive work from the Foxes to finish at his second attempt after his initial shot was blocked.
Bobby De Cordova-Reid levelled with a well-placed half-volley two minutes after coming off the bench and the substitute was involved again in the build-up to James' 92nd-minute header that earned Leicester their first victory in six games.
What was only Leicester's second win in 11 games, dating back to August, will ease the scrutiny of Foxes manager Marti Cifuentes, but the result has Manning now seemingly clinging to his job at Carrow Road.
Norwich fans made their feelings clear as vocal outrage in the stands morphed into protests outside the ground.
Hundred of supporters gathered outside the directors' entrance to Carrow Road to chant their dissatisfaction with sporting director Ben Knapper, Manning and the board.
Norwich's eighth successive defeat at home, which extends their winless run to 11 matches in the Championship, leaves them second from bottom in the table heading into the international break
They had almost snatched the lead in the 13th minute when a Kenny McLean cross pinballed off Ben Nelson and James before goalkeeper Asmir Begovic and Caleb Okoli combined to keep out what would have been an own goal.
Jordan Ayew slammed a volley into the ground and over the bar, while Patson Daka sent a header wide for the visitors before Jovon Makama tested Begovic again.
Abdul Fatawu called Canaries keeper Vladan Kovacevic into action just before the break for the out-of-sorts Foxes, who lost Nelson to injury in the scrappy first half in Norfolk.
It only got worse for Leicester early in the second half, as their efforts to play the ball out from the back was disrupted and then punished by Kvistgaarden, who showed skill and poise to chest the ball down and finish after the rebound from his initial shot came straight back to him.
De Cordova-Reid, though, made an immediate impact off the bench to get the visitors back into the game with 15 minutes remaining.
A lengthy delay after Okoli suffered an injury added to the tense finish, in which James delivered victory from a Fatawu cross to leave Norwich supporters berating Manning with boos at full-time.
'We can't sustain intensity' - reaction
Norwich City boss Liam Manning told BBC Radio Norfolk:
"We were okay without, for me, testing their keeper enough, which has been a consistent thing around quality in attacking areas.
"When you look at the plan, the way we pressed, the way we got after them, the way we played forward and the way we were a bit more direct in what we did was good.
"But in the last 15-20 minutes we can't sustain the level of intensity that you need to and, unfortunately the challenge is to be able to have real impact off the bench to sustain the levels when we have the volume of injuries we have got.
(On fans' protests) "My whole thing is not to put on a sales pitch, my whole thing is to thank the fans today. I thought they were outstanding to the final whistle.
"In a tough moment and where we are at, I thought they showed what they are about today and really stuck with the group, which is the most important thing.
"And going forward that's exactly what the lads will need.
"I don't live my life with regrets, it's part of my journey. I'm learning, I'm hurting, I'm frustrated and I'm hugely disappointed because this is a club I care deeply about. I didn't come here to be where we are. But we are, so I will do a lot of learning as to why."
Marti Cifuentes: 'It was important for the whole group'
Leicester City manager Marti Cifuentes told BBC Radio Leicester:
"It was very important for the whole group because it has not been easy days or easy weeks. The guys showed character, and we finished the game as the better team.
"The way we finished the last game (a late draw with Middlesbrough in midweek) had a big impact mentally, so to be able to respond from a mental point of view was extremely strong.
"From day one I've said it doesn't matter how much quality you have got, you need to be together, need to show commitment and this attitude because it is not the easiest league in the world.
"I think the guys are getting there. Cultural changes are the ones that time more time, so we are trying to get there. It will be up and down, for sure, but now we can reflect on what we have done well over the last couple of games and we need to keep working in this way and analyse what we can improve on."
