This is a Central Point Injection system. He could not check the injectors that easy. You need to get a thermal camera, or a temperature gun. Take a look at the temperature of the exhaust when the van is running. You will see that the cylinder #4 will be cool compared to the rest. Also you will see that cylinder #4 spark plug will be White in color, when removed. The electrodes of the spark plug will be white. That is a lean condition. That injector is bad. You will need to pull the intake manifold and replace the central point injection system as a whole. AC DELCO Central Port Fuel Injection for Silverado Sierra Express Savana...

It sounds to me that you may have 2 problems. 1). Air Lock in the Heater Core. 2). Inactive Heat Damper in the Plenum.

But since you state that the Heater Hoses do not get warm that is indicative of an Air Lock in the Heater Core. This is a relatively simple fix. It is best performed COLD but requires a method of pressurizing the Cooling System. All reputable Auto Parts stores Sell and/or Rent Pumps that temporarily replace the Radiator Pressure Cap for Leak tests and curing Air Lock. The Collant Level must be filled FULL then pressurized and then loosening the Highest Heater Hose at the Firewall so that Air and a Small Amount of Coolant escapes. Once all the Air has escaped tighten the Heater Hose Clamp, remove the Pressure Pump, Restore the Collant Level to FULL, re-install the Pressure Cap and Start the Engine. As it Warms up you should be able to feel coolant running through the Heater Hoses and they should become warm.

code p0420 refers to cat converter system, bank 1 efficiency below threshold===causes --cat converter--wiring HO2S sensor 2

check that the cat converter is ok and replace the sensor. ( it is a HO2S sensor which will be different to a O2 sensor so get the right one )

Why would you change any items?

Have you not googled the code?

420 & 430 are exhaust converter issues

You change no parts,you check for codes & component
test system faults using the codes, until you find a problem
