When does a misfiring engine fail an emissions test?
When a misfiring vehicle is subjected to an emissions test; it will usually fail. This is what happens when you feel your engine stops for a fraction of a second; then regains its momentum.
What happens if you have a cylinder misfire?
Ensure you consult a good auto mechanic to fix the problem quickly if your engine is misfiring. This is because misfires reduce gas mileage and increases emissions, which can cause you to fail an emission test. Cylinder misfires can equally cause damage to other parts of the engine, like the oxygen sensors or catalytic converter.
How does engine misfiring affect your gas mileage?
Consequently, Engine misfiring reduces gas mileage and increase emissions, which can cause you to fail an emissions test. More seriously, cylinder misfires can cause damage to other engine parts, like the (O2) sensors or catalytic converter. Engine misfiring occurs when ONE or more of these factors is wrong, missing or just not working together:
What is the diagnostic code for a misfire?
Misfires that turn on the check engine light and log a cylinder-specific fault code are the easiest to diagnose. A flashing check engine light and a P0301 to P0312 diagnostic trouble code (DTC) is a surefire indication that one or more cylinders are misfiring. Occasional misfires may pass unnoticed, but a steady misfire is hard to miss.

What are the most common failed emission test codes?
Small leaks easier to find, because to create a vapor-like smoke the machine heats the mineral oil, it may contain dye of UV leak detection. Cycle the purge solenoid and other EVAP self-test can be run using a professional level scan tool which have a bidirectional communication ability. 1. Low Fuel Pressure
