Can a faulty spark plug cause an engine to stop?
Faulty spark plugs will cause issues with the performance of the engine that is easily noticeable. Below are some of the common warning signs that indicate faulty spark plugs in a car. An engine misfire results in the engine to stop for a moment and then regain its normal operation.
What are the symptoms of a narrow spark plug gap?
The duration of the spark has less travel distance, thus not remaining hot enough with sufficient charge to ignite the air-fuel mixture. The symptoms of narrow gap include a noticeable (continuous) cylinder miss, hard starting if all the plugs have narrow gaps, rough idle and engine hesitation.
What causes engine to hesitate at low rpm?
If any of the vacuum hoses around your engine become damaged or worn out, you could experience air leakage from them. Then you will experience engine hesitation which is most noticeable at low RPM. Repair or replace any hoses which are causing the leak.

What are the symptoms of a bad spark plug?

What causes engine to jerk under light acceleration?
It is not a coil or air mass meter because you have no fault code for it. Maybe a air leak on the inlet manifold but this would show up as running lean. There is no spark plug leads. I would change the fuel filter, it takes very low/high pressure to bring a fault code up for this.
Why does my Jeep WK2 surge while driving?
It mainly did it going up hill or at around 40 mph at 1300 rpms. Just like the WK2 guys with the 3.6 engine. They are experiencing something similar with having to adjust the way they drive due to lack if power and not so good tuning. It’s going to surge/buck regardless what you do because of lack of power and tunning.

The car idles and drives perfectly at slower speeds but on the highway you can really feel the pulses and hear the exact making sounds.
Why does my car sputter when I Turn on the engine?
The fuel filter ‘s job is to filter the fuel going to the fuel injectors and then enter the engine. A clogged fuel filter can cause the engine to get too low fuel pressure or cause a clogged fuel injector. Low fuel pressure will cause the engine to run very leanly, and therefore it may cause the engine to sputter.
Can a bad spark plug cause an engine to vibrate?
Rough Idle. A bad spark plug may cause your engine to sound rough while idling. The vehicle-encompassing, jittery sound will also cause your vehicle to vibrate. It can indicate a spark plug problem in which a cylinder misfires only while idle.
How many spark plugs are in a cylinder?
Some have two spark plugs per cylinder. Some head designs are more prone to cracking. Others are more prone to warping. Some are still cast iron, others are different alloys of aluminum. The only common similarity is they hold the valves and spark plug, and contain the combustion.
Do you need four prong spark plugs on Mercedes Benz?
Unless specified in your owner’s manual, you should avoid four prong spark plugs on Mercedes-Benz engines. Incompatible spark plugs can even trigger the check engine light. Not only are they more expensive but they can cause sputter, misfire and decrease fuel economy. Copper vs Platinum or Iridium. What’s best?
Which is hotter a hotter spark plug on a Mercedes Benz?
We recommend to run colder plugs. If you use hotter spark plugs you may experince pre-ignition issues. The higher the number the colder the heat range. Spark plug heat range on most Mercedes-Benz cars is 6. Which are some Mercedes-Benz engine numbers? Your Mercedes-Benz has over 100k miles.
