Let

cold engine run at slightly higher idle. This

will

the outlet pipe from EGR filter t o

EGR

valve.

Increase engine speed t o about

4 , 0 0 0

rpm. The

outlet pipe from the EGR valve t o t h e intake
housing must now b e hot, too.

If  the outlet  pipe between  the EGR  valve and  in-
take housing  is  not  hot,  the following  conditions
could  b e  causing  this:

a) EGR valve defective

b) EGR lines plugged

c) Vacuum bores in throttle valve housing plugged

d) Vacuum hoses plugged or leaking

e) EGR filter between muffler and EGR valve

clogged
