WORN OUT AND DAMAGED SPARK PLUGS OR WIRES
The check engine light is one of the signs that your engine is having spark plug problems. The (ECM) is far more sensitive than many drivers and can detect a single cylinder misfire. If you get a check engine light along with slight jolts while accelerating, the spark plugs could be to blame.
STEPS TO REPLACE SPARK PLUGS:
1. Get Access to The Spark Plugs
This might require removing other parts, such as engine covers, heat shields, or the intake manifold.
2. Remove the Spark Plug Wires And Or Ignition Coils. Before removing wires, use tape or some other means to mark their correct locations. Replace scuffed, worn, or damaged spark plugs wires or boots.
3. Use Compressed Air To Blow Out Spark Plug Holes. Debris tends to collect in unprotected spark plug tubes and channels. Using compressed air is a good way to get rid of it. Also, preventing it from falling into the cylinder, when you remove the spark plug.
4. Remove the Spark Plugs, Using a spark plug socket, remove the old spark plugs.
5. Recheck the Spark Plug Gap. Most new spark plug gaps are preset from the factory. But, it’s a good idea to check and adjust the spark plug gap, just to be sure.
6. Lubricate New Spark Plug Threads. Using just a dab of anti-seize lubricant, silver or copper doesn’t matter; lubricate the spark plug threads and gasket.
7. Install the New Spark Plugs. Turn the new spark plug in by hand until finger tight, then torque to specification. Gasket types usually specify a quarter- to a half-turn after contact. While, non-gasket types specify just a sixteenth-turn. Check the manual to be sure.
8. Reinstall Everything Else. Finally, reinstall wires/coils and all other parts. Such as engine covers, heat shields, or the intake manifold. Being observant is key to keeping a reliable car. And, recognizing spark plug problems early, can improve fuel economy and prevent you from being stranded.
9. And don’t forget to check the wires if they’re the main problem they might need adjustment or replacement. Do that if needed.
