1995 toyota 4 runner vacumm problem.

I just had a recent head job done, due to car overheated and blew my
heads, The car is working, but its idling kind of rough and is also my
my check engine light is comming on. I had a friend of mine check it
with the diagnostic computer and its is giving me a 71 code. Its
supposed to be my EGR valve that is supposedly stuck. Is there a way to
verify if the EGR is trully stuck in an open or shut off position? or
if it is a EGR system problem and one of the hoses is in the wrong
location. If anyone can help out, it would be greatly appretiated.

The EGR valve, if I'm correct, is on the rear passenger side head, covered
by the intake manifold. I was told it should be cleaned or replaced if you
were ever to remove the intake manifold/plenum. Since you had your heads
done they should have replaced it. It might still be under your warranty.
If not you'll have to remove the intake plenum.

Do a search for a shop manual for your year and model. BTW is it a 95 or 95
1/2 4Runner?

Thanks for the reply, but I think your thinking of the PCV valve. The
one under the intake manifold. The valve was replaced when the heads
were done with a new one as it would be hell trying to replace it after
the intake manifold was placed. The EGR valve is the one located in the
front of the intake manifold that looks like a little saucer on the
passenger side connected top a bunch of small black hoses. I am also
curious if the EGR valve malfuntioning would impede my cruise control
from working. I seriously have had bad luck with this truck, but put
too much money into it to throw in the towel just yet.

Maybe your right, I have to look at my engine again, but I part your
describe is the Air Mass Meter. It has a wide rubber booted connector.
