you need to check the manual to be sure about this, but i don't think
there should be vacuum on that line all the time - only when the ecu
considers the load appropriate. besides, the actuators for that stuff
are /very/ reliable. first likelihood is that the egr valve is getting
clogged. take it off & clean it up. use a wooden spatula to remove the
gunk from the moving plug contraption, not metal - avoids scraping & gas
leakage. and the gasket will likely fall apart on removal of the egr
assembly, so buy a replacement before you start.

Hi All....

I have a little problem with my 1993 Honda Accord EGR system. The car
has 171K miles. The Engine runs fine at idle except for a slight,
inconsistant miss. Then the car has a slight hesitiation at about
1500-1800 RPM. Other than that, the car runs fine.

I checked the hose (#16) that goes to the EGR value and I determined
that it has NO vacuum in it (at idle or above 2000RPM).

What would cause NO vacuum to the line to the EGR valve?

A previous post said it might be the EGR solenoid.

How can I tell if the EGR solenoid is faulty?

I will admit to knowing very little about Hondas, but I really want to
learn.

Can someone please offer me advice to fix this problem?

Hondas are great cars and I would like to keep this one running for a
long time :-)
