oven pilot issues believe gas valves

model number vg60f-57

Problem dual oven. right side when u light pilot flame looks good till u release it, flame is very low. New thermal coupler. pilot flame less then 1/4 in. When stove on right is lit only 1/2 burner lights.

Left side stove trying to light pilot, it is to low of a flame. New thermal couple was also installed, but flame will not stay on.

I was thinking gas valves for each oven. Top burners work great.
