It is important to be aware of signs your engine might be failing. Although most vehicles today are equipped with a check engine light to warn of potential problems, you should also understand the warning signs your vehicle may give you. Engine failure can mean expensive problems as well as the risk of being stranded. 

When you see that check engine light it might be tempting to ignore it, but you really should schedule diagnostic services to identify the problem. Aside from your check engine light, here are some additional indications that your engine performance might be lagging or your engine might be failing:

Is Your Engine Losing Power?

The function of an internal combustion engine is to convert fuel into the power needed to move a vehicle. Combustion engine operation involves a four stroke cycle – intake stroke, compression stroke, combustion stroke, and exhaust stroke. Failure during any one of these strokes could result in a lack of power to the engine and poor engine performance.

Are You Hearing Strange or Excessive Noise?

Interference in the combustion flow can result in unusual sounds such as knocking, hissing, popping or backfiring. Whenever you hear odd noises when you start up your vehicle, consider it a warning sign.

Have You Noticed a Drop In Fuel Efficiency?

If you’re not getting the miles per gallon you used to, it could be a sign that there is a problem with the compression stroke of your engine. Fixing this issue could be as simple as having the fuel system cleaned or getting a tune-up.  

Has Your Engine Been Stalling? 

Engine stalling in automatic transmission vehicles is highly unusual and likely a sign of trouble. The intake stroke might not be getting the spark or air/fuel mixture it needs. The problem could be serious and should be checked. The solution could be as simple as a tune up.

Are You Noticing Engine Run-On or Running Rough?

Does your car continue to run after it’s turned off? Does the engine seem to be running rough?

Engine run-on could be caused by incorrect octane gas for the vehicle, a failing solenoid, or carburetor issues. A failing battery, clogs in the system or old spark plugs can cause a rough running engine. So can incorrect octane in the gasoline in the tank. Once again, a simple tune up could be all it takes to remedy these problems.

Pay Attention to Signs That Your Engine Might Be Failing

Just like the check engine warning light, you should not ignore these signs when they occur. Addressing engine issues early can help you avoid serious consequences.
