Sad 93 sl fails smog SES & high NO

I thought it would pass.. it passed last year.
The darn Service Engine Soon light came on during test
and the NO at 15 mph was 787 (720 max allowed)
I will take it to my trusted mechanic (who is not a
Saturn specialist) and hope he can figure it out.

(the evaporative test passed)

ever since I bought this car a year ago the SES light has come on
when I drive on the freeway or long distances. My solution was
to stay off the freeway and only use it near home shopping etc.
Now I find I must deal with the horrid SES. lol lol

I don't know the code and my trusted mech told me to skip the
paper clip as it could be trouble for me.
But what about the 787 NO ?? any ideas out there?
thanks
zigi

REWARD EXCELLENCE!

High NO usually means you have a dirty EGR.

Well, without a code I have to use the crystal ball and it says EGR and/or EGR solenoid.

Dizzy Re: 93 sl fails smog SES & high NO

thanks guys yeah first thing in the morning george will be checking the code on the SES and checking the egr and the egr solenoid !!
fingers crossed its a simple and cheap operation.

those smog guys scared me when they did the new evaporation test..
one guy put this probe under the hood and then screwed my gas cap
to a large rectangular device with key pad on it.
In typical female fashion I got nervous and said WHAT are you doing to my car???
The smog tech must have been Moslem before getting to my smog check he was behind the garage on his prayer mat. That was fine by me since I
do yoga and meditate every morning, but he was on and off his cell phone the whole time he did my test. I felt so not served. I do have to go back there for the re test so hopefully I caught him on an off day.
anyway thanks again and I'll post the results !!!
