[DeTomaso] NPC-1988 GMC Smog Test

Congrats!

      Great news to report!  Fully expecting  to fail my California smog
test,  (after nearly failing two years ago),  I was amazed when I passed
with flying colors!  I mean I didn't just pass,  I smoked the test!  No pun
intended.  My truck put out maybe 10% of the emissions it did two years ago!
In preparation for this year's test,  I did four things different.  First
off,  I added one quart of the Lucas Heavy Duty Oil Stabilizer.  Next I used
the CRC Guaranteed to Pass,  Emissions Test Formula,  Complete Fuel System
Cleaner.  I replaced my standard AC Delco spark plugs that had 99,000 miles
on them.  The same plugs had 73,000 miles on them during the last test two
years ago.  (Maybe that was my Problem).  Finally,  I got the engine good
and hot before testing.  I drove to the facility in lower than normal gears,
turning higher rpms.  I want to thank all of you guys that responded,  for
your help.  It was much appreciated!

       I have a 1988 GMC 2500 3/4 ton pick up truck that has to be smog
tested here in California this month.  Two years ago it only passed by the
skin of it's teeth.  In the 15 mph Hydrocarbon test,  it blew 115 when 116
is allowable.  So,  I am pretty sure it is not going to pass this time.  My
question is,  what can I replace to at least have a chance of passing?  I
failed the hydrocarbon test four years ago and after replacing the catalytic
converter,  I passed,  but not with flying colors.  The catalytic converter
has about 50,000 miles on it and the EGR valve is six years old with about
80,000 miles on it.  The oxygen sensor is almost six years old with about
75,000 miles on it.  The engine is still running good after 282,000 miles.
I'm guessing that an engine rebuild would solve the hydrocarbon problem but
of course,  I don't want to do that.  Any suggestions?

  Thanks,
  Art
