Preventive maintenance such as replacing the spark plugs can make a high mileage engine easier to start, improve fuel economy, lower emissions, restore lost pep and power if the old spark plugs are worn or fouled. But if the engine is not running well because of some other issue (such as ...
Car engine surge can cause the engine to lose the RPMs for a moment and suddenly regain it at normal speed. This is usually caused due to an issue in the car’s computer system. Besides, there can be several reasons behind engine surges, depending on the vehicle’s specifications. If you...
Engine misfires– insufficient or weak sparks can lead to faulty combustion, resulting in engine misfires, reduced power, and increased exhaust emissions. Difficult starting– a telltale sign is when a failing ignition coil can cause difficulties in starting the engine, especially during cold weather...
Mechanical misfire: This is when the engine has worn out due to a slipped timing belt or chain, a tattered belt or chain tensioner, or a damaged valve. Mechanical misfires are very serious because the timing between the piston and valves is off, and the two are at risk of colliding and...
Your engine has a misfire. You need to get the codes scanned in the computer to even guess what may be wrong. One thing is for sure, it is NOT the gas cap! Code readers of any kind will not get the codes to flash. Even the manual jumper to get the codes to flash doesn't ...
Even though a loose gas cap is the most common cause, don’t assume a Check Engine light is always minor. Some serious problems—like an engine misfire—can also trigger the light. That’s why it’s always worth checking out sooner rather than later. Is it OK to drive with the Check...

When an ignition system failure leads to a misfire or other similar malfunctions, a scope is often used to determine which cylinders are misfiring and what the potential cause might be. Scope patterns can often be used to determine whether a plug is fouled, a plug wire is bad or shorted,...
Weakening engine performance: A knock-on effect of misfires, acceleration and overall performance will suffer if any of the cylinders fail to ignite its fuel mixture. This is a telltale sign of spark plug failure. Rough idling and loud engine noises: When a spark plug isn't working, the ...
