'87 Chevy Sprint NA
Stock 4 door
HC measured 9 and 2 ppm (107/89 allowed)
CO measured 0.0 and 0.02 (.64 and .56 allowed)
NOx measured 562/419 (906/845 allowed).
First number is the low speed result; second number is the high speed result.
This engine is going on 10 years since last refresh.
The oil is very clean and there is little consumption between changes.
5W-30 Mobil 1 EP
Catalytic converter? CARB compliant CAT about 4 years old.
This smog test result tells me it is time to roll up my sleeves and get busy with the emissions equipment.
That EGR valve and/or its passages are probably getting clogged, or it could be the EGR modulator.
Maybe the carburetor is in need of a rebuild.
Still, in 15 years of driving the car, I am not complaining.
I don't know who has bad luck with Suzuki cars, but not me.
Odd ball items have occurred come to think of it:
-alternator went out in Oregon
-float valve stuck about 10 miles from home a few months ago...I didn't even bother to rebuild the carb. I just fixed the float valve.
People who post threads trashing Swifts, Metros, and Sprints probably approach their cars with a different attitude.
Or they don't know how to properly work on their cars.
You get an old one, clean it up, put it back to specs and take care of it, and she'll last for years.
You pay someone to do your dirty work and you may get screwed.
It isn't anything fancy to look at,
but it gets the down the road just fine, thank you.
I'm not sure how fast it goes, but I did run the needle over to where the 7 or 8 o'clock position is once or twice.
Cops?
They don't even give me a second look.
There are too many high end cars on the road begging for a speeding ticket; why stop a Sprint?
Ha!
I'll admit I was a bit lax before taking it in for the 2015 smog test.
Next time I run it through the State's dyno/sniffer, hopefully that NOx will be down, down, down, to Chinatown.
Clean the EGR and put a new oxygen sensor on it.
Meanwhile, it's still clicking off decent mileage - 44+mpg on the last tank, and you can see I DON'T drive 55.
Smog tests don't scare me.
They used to.
If you know what you're doing and understand the fundamentals, you can get your cars to pass a smog test.
If your car burns clean, you'll see it when they sniff your tailpipe.
And this vehicle is OBD I - more difficult to maintain than the OBD II's.
My friends outside California?
They get REAL NERVOUS when I innocently offer to pay for them to run their car through a smog test station out here.
If they're great mechanics, these California smog tests will show how great they've brought their car into specs.
BTW: I'm talking about daily drivers, NOT vehicles modified for another purpose.
Who's afraid of the big bad smog???
Bring it on!

, or ask the tech who has the records in front of him when he does the testing.
fortunately it did better on the second run.
