What causes a snowmobile to misfire?
You are advised to check your engine, exhaustion, plugs, pipes, fuel mixture, etc. Here are some potential factors that cause backfires: The spark plug(s) might be damaged, overused, dirty, or wet. Too much fuel or too much air doesn’t allow proper ignition.
What is the most reliable Ski-Doo snowmobile?
In addition to being durable – a basic requirement to be listed among the most reliable snowmobiles – the Ski-Doo Expedition Xtreme 850 E-TEC comes with very solid functionality via its Cobra WT track that grips deep snow with ease, keeping you on course.
What should I do if I have a misfire in my engine?
Addressing Electrical or Mechanical Misfires Inspect the spark plugs for signs of damage. Use a multimeter to test your coil pack. Do a compression test if air, fuel, and spark seem to be in order. Replace the head gasket if nearby cylinders don’t have compression. Have the bottom end of the engine rebuilt if there’s a serious lack of compression.
Is the Check Engine light still flashing after a misfire?
The check engine light will flash as the engine misfires, but it may stop if the misfire stops as well. If your check engine light is not flashing but you see other signs of a misfire, the engine may still be misfiring. Scan the engine’s error codes.
How does the engine control module detect a misfire?
The engine control module is using a lot of sensors to know when to ignite the spark plug and when to inject the fuel into the cylinder and to optimize the air-fuel mixture. To detect a misfire, the engine control module is often using the crankshaft sensor to detect a misfire.
How can problems with the ignition system cause misfiring?
There are several potential ways that your ignition system problems could translate to a misfire: Worn Out Spark Plugs: If your plugs are worn out, then the electrodes have gotten too short to provide the right amount of spark. This is a gradual process, and is the reason that you need to replace the plugs on a regular basis.

Addressing Electrical or Mechanical Misfires Inspect the spark plugs for signs of damage. Use a multimeter to test your coil pack. Do a compression test if air, fuel, and spark seem to be in order. Replace the head gasket if nearby cylinders don’t have compression. Have the bottom end of the engine rebuilt if there’s a serious lack of compression.
What causes the spark to go out in a misfire?
Ignition misfire. As the spark plugs, ignition cables, distributor cap and rotor, and ignition coil wear over time, their ability to transfer the needed spark to ignite the air-fuel mixture inside the combustion chambers becomes compromised. In the early stages, the spark will only be weaker and the actual misfire will be subtle.
How do you check the fuel level on a snowmobile?
The floats can be checked by taking the bowl off, turning the carb upside down and measuring the float arm height. It is adjusted by bending the tang in the center of the float arm. You can also check the fuel level in the bowl using a fuel level gauge.
