Symptoms of a Failing Spark Plug
Worn or fouled spark plugs can cause a number of noticeable issues with your Volunteer's engine. Because these symptoms can also point to other fuel or ignition problems, it's a good idea to check the spark plugs first, as they are an inexpensive and easy part to inspect or replace.
- Hard Starting: If the engine cranks but struggles to start, or won't start at all, a weak or non-existent spark could be the cause.
- Rough Idle or Stalling: A dirty or worn plug can misfire at low speeds, making the engine run unevenly or even stall.
- Engine Misfires Under Load: You might notice the engine sputtering or losing power when you're accelerating or going uphill. This is a classic sign of a spark plug that can't handle the demand.
- Poor Fuel Economy: When a plug isn't firing efficiently, your engine has to work harder and burns more fuel to produce the same amount of power.
- Black, Sooty Plug: If you pull the plug and it's covered in black soot, it's a sign of fouling. This can happen from running too rich or from excessive idling. A fouled plug will struggle to create a strong spark.
