My 81 just failed smog :-(
Looking for opinions before I go back to another facility (the
test-only guy was not very helpful, I think he's in cahoots with the
repair guy who referred him, not that I'm cynical or anything )
So, I'll just throw out the numbers, and see if anyone has
15 MPH .94 MAX .93
25 MPH .99 MAX .73
15 MPH 1300 MAX 1097
25 MPH 1117 MAX 927
Any help appreciated. I'm in the SGV area of So. Calif. if you know an
Sorry to hear of your smog check results.
Generically speaking it might be a couple of things.
Regarding CO: Sounds like a weak catalyst to me .
Re. NOx: The EGR valve may not be flowing enough gas.
BTW, What were the measured amounts of CO2 and O2?
Just a general note on this for folks new to California.
Don't ever make your first visit to a "Test Only" facility even if the
DMV required a TEST ONLY place on your registration renewal. If you are
required to certify at a "Test Only," first go to a regular full-service
smog station, get the car "voluntarily tested" and, if necessary, fixed
(or fix it yourself) before you go to the TEST ONLY station for
certification. One clean test without problems should get your car off
the DMV's TEST ONLY list for the next go-around. This 2-step process
will cost you an extra $ 35 to $ 50 bucks but save you mucho time.
"Test Only" places are where DMV sends cars or engine types that are
suspect (age of car, high mileage on last test or resale, prior "major
polluter" status, engine type with history of problems, etc.). The Test
Only outfits were a creation of the Sacramento politicos to spread the
money around to businesses with no talent, tools or repair license. It
was a means to attract capital investment to pay for the dyno/wheel load
equipment a dozen or so years ago. Now we are stuck with it. Strictly
a rip-off at smog time!
Sorry if some reader runs a bunch of "Test Only" shops. JMO
I took my 77 in to a Test Only shop and had them do a test run on the car
before they hooked up to transmit to the State (California). The cost was
an extra ten dollars. I figured the car would pass okay, but I wanted to be
sure first. The Test Only center will do a test run, but if the car doesn't
pass, they aren't equipped to tell you what the problem is. I just do it
for the insurance factor that if for some reason the car doesn't pass, the
information will not have been passed on to the State. If it is, the
vehicle is classified as a "gross polluter" and you have to have it tested
every year for a while.
