Reader Question: Hello:
I have to get my 1990 Toyota Celica smogged. In 7/2008 it barely passed.
The test said that under the
NO(PPM) max=807 and aver. = 237/i had 738 at 15mph
max=746 and aver. = 199/i had 696 at 25 mph
I am in Calif. What are the least expensive things i can do to help it pass the test? I was told (by a Ferrari mechanic) it might actually do better because the engine it came with when i bought it was relatively new (rebuilt) and it may have adjusted better thru time (20,000 miles later)to the pvc valve. He said he was saying that because it was a possibility…but not necessarily a likelihood.
What do you advise?

Howdy Howard,
In Texas you get 2 chances to pass the test before you really have to spend money and do something about it. Most of the vehicles that I see that fail, a new catalytic converter will mask the problem enough to get a passing score. I would have to run some tests on your vehicle to be sure, but if you are just wanting to guess at something…then I would have a local muffler shop install an aftermarket converter and cross your fingers. Costs about $225 here in Houston.
I would also change your oil, drive the vehicle on the freeway for 10 minutes before testing and make sure the engine and coolant are good and hot before you test.

I love how Toyota showcase their product. From engine up to the outer design, its all amazing. Wish I can have my own car soon.
