Yes, it can. Other causes include ignition and fuel systems.
the answer is yes
MaybeMaybe
Clogged injector, burnt valves, blown head gasket, bad intake gasket. spark plugs.
If the leak is bad enough i believe it can but i would check your valve cover gasket first.
THE CAUSE COULD BE A STUCK THERMOSTAT , OR A BLOWN HEAD GASKET, OR A LEAK IN THE INTAKE MANIFOLD OR INTAKE MANIFLOD GASKET. A CRACK IN THE INTAKE MANIFOLD IS VERY COMMON.. NORTY
Vacuum leak or blown intake gasket.
I don't think a blown intake gasket would cause it to overheat, Most causes of overheating are: thermostat stuck in closed position; faulty water pump; broken fan blades; loose belt; clogged radiator; radiator cap not holding pressure; blown head gasket; low or no coolant; leaking hoses.
The Intake gasket is leaking, NOT THE HEAD GASKET. Replace the intake gasket
That would probably cause it to run lean.
I blown head gasket can cause an engine miss which one cause a rough idle.
yes if its stuck closed.
Yes, I blown head gasket will definitely effect the emissions.
