I have 1994 Chev. Corsica with a 6 Cyl. engine, 150,000 miles. It
started giving me a check engine light, and had it run on diagonostics
and it said there was a problem with the EGR valve. Since it is
easily accessible I took it off and cleaned it thoroughly, and it ran
fine, other than the check engine light still came on occasionally.
Now, I am having additional problems, and was wondering if the valve
had went bad what would the symptoms be. Right now, it will start
sometimes, and run just fine, and then it will not start at all, acts
like it is not getting any fuel. Would appreciate any help. I do not
have a problem changing out the valve myself (just 2 bolts and an
electric connection) but would like some advice as to whether this
could be the problem.
