Can a bad ignition coil cause engine to shake?
When an ignition coil fails, it’ll cause a misfire, or failure to ignite the air-fuel mixture. This failure to ignite “kills” the cylinder; the “dead” cylinder causes an interruption in power production in the engine, causing it to shake and jerk.
Why is my car still shaking after replacing spark plugs?

Can a bad ignition coil cause a bad spark plug?
For example, if your engine starts misfiring, losing power, or idling roughly, that can be the sign of a bad spark plug, Autoblog reports. But those signs could also point to a faulty ignition coil. A check engine light can also point to either, as can difficulty starting the engine.
What to do if your spark plugs don’t work?
Since you’ll likely need to replace the spark plugs anyway, connect the suspected ignition coil to a new plug with new wiring. If it still doesn’t fire, it’s the coil. Or, simply unplug the wires from each cylinder one at a time. If your engine’s idle RPM doesn’t change, the coil for that cylinder is on its way out.
Why do diesel engines not have spark plugs?
Diesel engines don’t have spark plugs because diesel ignites via compression, not a spark. Ignition systems have evolved over the decades, Champion Auto Parts explains, but they work in broadly the same way. There are 2 parts: the primary ignition and the secondary ignition. The first comes into play when you press the start button or turn the key.

What happens to the spark plug when the engine is running?
When your engine is running, just when the piston compresses the air-fuel mixture, the spark plug fires and ignites it. The ignited mixture rapidly expands, forcing the piston downward, which is converted to rotary motion by the crankshaft.
What should I do if my spark plugs are worn?
Solution: Clean the throttle body and clean or replace the IAC. Clean, repair, or replace idle-up switch or vacuum lines. Worn spark plugs might not ignite the air-fuel mix as efficiently, leading to weak combustion or a misfire. In each cylinder, one or two spark plugs provide the spark that ignites the air-fuel mixture.
How many coils are in a spark plug?
Most modern vehicles have one ignition coil per spark plug, controlled by the ECM. Older vehicles may have one ignition coil per pair of spark plugs, ECM-controlled waste-spark systems, or mechanically-controlled distributor with a single coil and spark plug wires.
