Question about Cars & Trucks
It doesn't have a heater control valve. You might have the heater hoses on backwards. Try switching them.

The best thing to do is to buy a Chilton,s repair manual. It has step by step procedures. You can get one at most auto parts stores. They coast anywhere from $10-$30 dollars.

if the air is definatly being blown through the heater core , then the core is blocked.if there is no hot coolant passing through the core then ------no warm air ---give it a good look see if you can see the deflector guiding the blown air is going far enough to send majority of air through heater good luck

If yours has a control valve, it will be inline in a heater hose just ahead of the firewall. before taking it out make sure it has a vacuum line attached. If I remember correctly, default is heat. I hope you checked the vacuum motors on the heater box and made sure that the plenum doors are operating and not jammed while you had it out!!

As far as the poor running and hard starting, yes, it could be egr or valves or timing or almost anything. Your heat problem : I suspect the heater core may be air locked. With the engine running, loosen one heater hose with the heat control on hot, and see if you can get any air out of it.
Also, check your water pump. Squeeze your rad hose as tight as you can for a bit. When you release it, you should feel a surge of coolant go through it.
Check your heat control valve to see that it's working.
