Hello everyone,
I'm having problems getting my 92 240 (auto., 183,000 km) to pass emission test.
The day before going to test, I changed oil and filter (running Mobil 1 synthetic 5W30 in it since 1999 when I purchased the car used), and catalytic converter is 2.5 yrs old, no dash instrument/warning lights are on, air filter clean 1 yr old, tune up done Oct/09.

Readings for the ASM2525 Test are:

Limit: Reading: Result:

HC ppm 62 21 PASS

CO% 0.35 0.12 PASS

NO ppm 467 1147 Fail

RPM 1812 VALID

Dilution 15.9 VALID

Can anyone help please on passing Nox emissions, wife would like to buy new car but I want to keep it. I'm located in Toronto, Ontario.

Any advice/tips is greatly appreciated.

Thanks
