So these damn codes came up with the usual VT 4 .. now it does a new issue I have to let the old girl warm up fully or she stalls out completely. Things been replaced are plugs , egr valve , maf sensor , o2 sensor , pvc valve , valve adjustment . Also notice the throttle body sticks when gas Pedro is pressed cleaned the butterfly still isn’t resolved. Fuel injectors rebuilt , fuel pump replaced due to float issue . All this was not done at once but still have this stupid issue.
