any trouble passing AirScare?

blowfish

Here in BC there's Aircare, yesterday I took my F350 Diesel Auto trans for test. The lady dump the gas pedal too hard cause a spike in Opacity to shoot up. As they give a time curve print out. I see all along the level was way below the norm, suddenly for 10 secs it spiked up. I went back to speak to the Manager, she agreed a re-test was done. And thank God she passed.
So the way the tester drive your vehicle could affect the outcome.

The retest didn't cost you money right?

of course it affects the results la...that's why they need to follow that pattern

last time the tester kept my car in 2nd gear at cruising speed...horrible...don't know how to drive manual???  I was afraid that my car would fail because of that...

Quest

For diesel (opacity test) yes, it is somewhat governed by the driver whose performing the test for you.

Mind you thou: 2 things come into play: (a) the most recent ultra-low sulphur diesel that WA is already mandated (available from most WA gas pumps along the highway) are very, very low in smoke, which in turn, can be translated to "low opacity"

(b) tuneups. If your diesel engine hasn't receive a proper tuneup in over 60,000kms or so, might as well do it (remember to drain and replace the fuel filter, replace the air filter as well) and make sure that your are not squirting too much fuel during acceleration (which leads to excessive smoking).

No I didnt have to pay again.

Dirty Fuel filter will not let more fuel pass thru.

Dirty air filter will restrict air so it can make the diesel run more richer.
I didnt put low sulphur fuel in it.
