Either catalytic converter or EGR (exhaust gas recirculation) system issues.
Yes if it is emissions related.
A car may fail an emissions test due to a variety of factors, including a malfunctioning catalytic converter, which reduces harmful exhaust gases, or issues with the oxygen sensors that monitor air-fuel mixture efficiency. Additionally, problems with the fuel injection system, worn spark plugs, or engine misfires can lead to increased emissions. Other potential causes include leaks in the exhaust system or the presence of diagnostic trouble codes (DTCs) in the vehicle's onboard computer. Regular maintenance and timely repairs can help prevent failures during emissions testing.
That will cause you to fail an emissions inspection. Anything which triggers the CEL will, because everything which triggers it will adversely impact the emissions system on that vehicle.
A dirty fuel filter could force a lean condition causing the check engine light to iluminate. In which case the vehicle would fail an emissions test.
Yes, a 1994 Subaru Impreza requires a catalytic converter as part of its emissions control system. The catalytic converter helps reduce harmful emissions by converting harmful gases into less harmful substances before they are released into the atmosphere. If the catalytic converter is removed or malfunctioning, it can lead to increased emissions and may cause the vehicle to fail emissions testing. Additionally, it is illegal in many places to operate a vehicle without a functioning catalytic converter.
you will fail the emissions test.
Performance may be okay but you will probably fail an emissions test.
Usually it is the O2 sensor
Yes, it can if faulty or missing.
No, but you will fail an emissions test.
The vehicle will fail an emissions test.
The airbag light would have nothing to do with emissions. If they are doing a safety inspection, it would fail.
