FlrSupra Posted June 4, 2010 Share Posted June 4, 2010 Hey. Having little emissions trouble on my N/A -94. Local MOT here in Finland complained about high HC-value on idle. The value should be under 100 and I got reading of 565. With revving the value dropped to 86 and that is good. But that really high HC value on idle still bothers... Any ideas?

Swampy442 Posted June 4, 2010 Share Posted June 4, 2010 Do you still have the cat? If so take it for a good drive, get the car nice and warm, a cold cat is useless Check the air filter as well. Link to comment Share on other sites More sharing options...

FlrSupra Posted July 11, 2010 Author Share Posted July 11, 2010 (edited) Finally I got Oxygen sensors changed for my N/A. I hope it will help on the next emission test. Edited July 11, 2010 by FlrSupra (see edit history) Link to comment Share on other sites More sharing options...
Nic Posted July 11, 2010 Share Posted July 11, 2010 The new O2 sensor looks like a genuine Toyota sensor, the old one is definitely not a genuine Toyota part. Link to comment Share on other sites More sharing options...
