80% Gas Furnace shutting off and on every few minutes

Good afternoon, recently installed a few inducer motor ( not sure if its related ) but a day after I noticed the blower motor would shut off and come back on a few seconds later every few minutes.

So I went downstairs to check it out, and what happens is that the burners turn off and on every few minutes. What I also noticed is that the flames are spread across the fins of all the burners? is this normal?
