Hi everyone, Im really at the ropes of my neck right now after trying to smog my bmw e30 325e. The main issue being my NOx readings being incredibly high.
My first run was 2078 NOx
My second run was 1782 after replacing the catalytic converter.
Third run shot back up to 2002 after replacing the O2 sensor, new spark plugs, and new rotor.
The minimum being around 700
I am getting another O2 sensor by warranty because I believe it is defective. Ive read other post and plan on using the sea foam cleaner, checking the fuel injectors, and looking for any leaks.
Any ideas of what might be going on and what to look out for?
Thanks.
