1993 Honda Accord Question: my 1993 honda accord fail smog to much nox
Timing and vacuum leaks are typical repairs. Is the cat original? - Hal...
95% of the time high NOX only is caused by a malfunction in the EGR system, if you want to bring it by, we will take a 15 min look at the vehicle at no charge - Vickersautorental
Check the egr systme first,common failure with the control valve,timing check cause you don't want to over look simple thing.. Third possiable bad catalitic converter... I would check the easy stuff first, timing,egr passage clogged,egr signal and cataltic converter..... - Rainbowauto
