i even passed the emission tests prior to the change oil and tune-up.
just make sure your engine is maintained properly, hindi naman dapat yan ginagawa lang prior to emission testing eh.
Yes, same here. With our cars they're just brought to the emission center for testing and pasado naman since they're maintained regularly and driven hard from time to time (redline, high speeds). Only once we failed and that was with our old B13 carburator Sentra since the carb set to be running too rich. After a quick tune up and tuning of the carb, it passed with flying colors.

The only instruction i give the driver is to not shut off the engine when waiting for their turn at the sniffer so as to keep the engine in it's optimal operating temperature for the test.
