Red is the Fuel pressure control, Not super critical, It closes during decal and idle to lower fuel pressure.
Blue is PAL valve, Not critical unless it is stuck open, It opens the PAL during decal to allow outside atmosphere into the
exhaust, Helps the CAT to run cleaner persay.
There should be a green one, That is EGR.
A grey one of you have airconditioning.
