I drive a 98 lexus gs 300 and it recently failed smog check bc the no levels are too high. How much would something like cost to repair
Mechanic's Assistant: What specifically didn't pass the test? When was your last oil change?
Dec of last yr my NO Levels are too high and I don't have the codes with me at the moment

So far I have just called around to a couple of local auto repair shops to get pricing.... i was told $120-$135 just to look at it

Good morning
The price for checking is right in line.
It could be either an EGR issue or bad cat converters not reducing the NOX to the correct level.
Let me check.
Roy
Are there any codes present at this time?

OK, NOX is controlled by the operation of the EGR valve as it lowers the temperature inside the cylinders to reduce the production of NOX.
Then the cat converter take the remaining NOX gases and changes them to harmless gases coming out the tail pipe.
Who ever checks it need to see if the EGR system is working as well as the cat converters.

Thanks. That is high.
I would suspect an EGR issue.
Are there any codes set?

Check engine light. See if it passed. If there were codes, that would have also failed.

I did not see it on the report. You can have a parts store check the codes for free. Then let me know the codes.
