Poor Ease of Idling
Poor Condition: The engine has significant issues with idling, such as rough or erratic idle speeds, frequent stalling, or constant fluctuations. There may be noticeable vibrations or stuttering in the idle, making the vehicle difficult to drive smoothly at low speeds. Immediate attention and repair are required to address the idling problem.
Read MoreFair Ease of Idling
Fair Condition: The engine idles unevenly, with noticeable fluctuations in idle speed or roughness. There may be vibrations or a lack of smooth operation, especially during startup or when the engine is at lower temperatures. Although the engine still idles, it may require tuning or maintenance to restore stable idling performance.
Read MoreGood Ease of Idling
Good Condition: The engine idles adequately, but there may be occasional fluctuations in idle speed or slight roughness. There may be minor vibrations or a brief period of rough idling during startup, but the engine stabilises after a short time. While the idle is functional, it could benefit from some minor adjustments to improve smoothness.
Read MoreVery Good Ease of Idling
Very Good Condition: The engine idles well, with only minimal fluctuations or slight vibrations. The idle speed remains steady, and there are no significant noises or irregularities. The vehicle starts and idles consistently without any noticeable issues, although there may be a slight idle variation during initial startup in colder weather.
Read MoreExcellent Ease of Idling
Excellent Condition: The engine idles smoothly without any fluctuations or roughness. The idle speed is steady, and there are no vibrations or unusual sounds. The vehicle maintains a consistent idle whether at cold start or after the engine has warmed up, providing a quiet and stable operation.
Read MorePoor Exhaust Smoke Condition
Poor Condition: The exhaust emits significant or persistent smoke, such as thick blue, black, or white smoke, indicating serious engine issues such as burning oil, coolant leaks, or incomplete combustion. The vehicle is not running optimally, and immediate attention or repair is needed to prevent further damage to the engine or exhaust system.
Read MoreFair Exhaust Smoke Condition
Fair Condition: The exhaust produces visible smoke during driving, such as light to moderate blue or grey smoke, which could indicate oil consumption or other engine issues. White smoke may persist for longer periods, indicating potential coolant leakage. The vehicle may still run, but further inspection and repair are recommended to address potential problems.
Read MoreGood Exhaust Smoke Condition
Good Condition: The exhaust may produce a small amount of smoke, particularly during startup or under heavy acceleration. The smoke is typically white or light grey and disappears after a few moments. While not a major issue, this could indicate the beginning of minor engine or system wear and might require inspection to prevent further…
Read MoreVery Good Exhaust Smoke Condition
Very Good Condition: The exhaust system produces only minimal or no smoke during normal operation. There may be a faint puff of smoke when first starting the vehicle, especially in cold weather, but it clears quickly. There are no signs of excessive smoke, and the engine runs cleanly.
Read MoreExcellent Exhaust Smoke Condition
Excellent Condition: No exhaust smoke is visible under any driving conditions. The exhaust system operates cleanly and efficiently, with no signs of emissions problems. The vehicle runs smoothly, and the tailpipe is free from any visible smoke, indicating a well-maintained and healthy engine.
