1 Gas Burner Flame too low

Have a Kenmore Gas Range w/ electronic ignition when you turn the front left burner on it either doesn’t or the flame is barely on. The spark electrode sparks well, I removed all 4 burners and lifted the top to inspect, thought it might be gas pressure but I turned gas on and lit gas orifice w a match and I had a strong flame, but when I place the surface burner base
and cap it will bearly light swapped burner base same results’
inspected burner base and it is completely clean. All other burners work properly.
