Angry Tricky Furnace.. Turns on and off going through cycle and wont turn on

I'll make this short and sweet.

Been living in our house for a little of 2 years the furnace is a York I have replaced the following items on the system to fix the issue

1. Thermal/Temp Sensor
2. "Glow Stick" "Sorry I don't know anything about Furnace's this heats up and ignites the gas to start the 4 burners"
3. Always changing the filter


Issues are I have my digital thermostat set at 68deg from 4-10pm 65deg from 10pm-6am. In this time period I hear the Furnace fan kick on for roughly 15sec then the flames come on and take off this is when I'm lucky.

Other times I'm experiencing the fans will start then just shut off then turn back on again and then the flames will come on. Other times when the Furnace is running the flames will shut off then the "Glow Stick" comes back on to reignite the flames finishing off the cycle to have the house heated at the temp I want. And as of lately the temp is dropping below my thermostat reading and wont kick on until I manually shut it off at the thermostat or at the unit.

I checked today for error codes the one that is popping up is "Lockout due to recycles" And when this craziness goes on with the multiple times it ignites there is no error codes normal operation codes.

Please help my wife and I with this issue, I'm getting tired of this and I'm about to pull my hair out over this .

Last thing I heard this may be caused by a "High Limit Switch" issue could this be true?

that does not mean it is not dirty.............

Remove and clean the burners and crossovers. Make sure ALL the burners lite. Ensure a good ground to the Gas valve or manifold.
