Gerard,
If your car has an EGR valve, that may be the culprit. The purpose of the
EGR valve is to lower the combustion temperatures in the engine, which
lowers the amount of NO produced.
A couple of years ago my truck failed SMOG for NO because the vacuum hose
running to the EGR valvle had a hole in it--I replaced the hose and it
passed.
We have had the "rolling SMOG checks" down here for several years now 8(

Well, time for my biennial SMOG check here in Kalifornia. If you
don't already know, last year they implemented a dyno into the
process and added NO gasses to the test. All my other reading were
extremely low, but I failed on NO (PPM) max at 15 MPH is 791 and I
read 965, at 25, max is 730 and I read 908. The odd thing is my car
overheated in the process (which it has not done in two years, ever,
and I'm wondering of that could cause the problem. If not, does
anyone know what needs to be corrected to drop this number?
Thanks for any help.
Gerard
