Spark Plugs Inspection and Replacement
Easy, Trustworthy Car Maintenance
Spark plugs are an integral part of your motor, providing the continual spark that ignites the air and fuel mixture within the cylinders. This interaction keeps your car moving on the road.
A failing spark plug is just one component on a long list of potential problems everyday drivers will contend with. Many auto systems depend on proper spark plug operation, so while a bad spark plug may not cause immediate symptoms, failing components in combination with a bad plug likely will.
Spark Plug Related Issues
A bad spark plug can be among the list of culprits for the following symptoms:
Rough Idle—Your vehicle shakes when it is standing still with the motor running. Can be caused by many things, including loose vacuum hoses and clogged filters; or it may be an electrical problem caused by bad wiring, distributor cap, or spark plugs.
Engine Misfires—The engine “hiccups” for a second, giving the feeling of a loss of power. Among the many causes are: faulty fuel injectors, distorted or failing valves and heads, bad ignition coil; of course bad electrical components like wires, computer systems, and spark plugs can also contribute to the problem.
Engine surges or hesitations—You are cruising along and your RPMs surge, or they may suddenly drop while in idle. There is a lengthy checklist to go through before the culprit (or culprits) can be found. This list may include: a bad fuel pump or injectors; faulty sensors or valve timing solenoid; a transmission lock-up, or spark plugs, among others.
Ignition Problems—When you turn the key, the engine turns over, but then a whole lot of nothing happens. There is a plethora of things that may cause this. Among the causes are: a dead or dying battery, alternator or starter; bad cylinder coils, distributors or connector wires; clogged fuel filter or bad fuel pump; or indeed, spark plugs.
These and other symptoms can be caused by old, poorly gapped or corroded spark plugs; but they are most often caused by a combination of things. If you experience these symptoms, or are just annoyed by that check engine light, come to Reis in Hales Corners or Greenfield for a diagnostic test now.
