Yes, Chevy Impalas do have coil packs. Coil packs are an important component of the ignition system in modern vehicles, including the Chevy Impala. They take the place of the distributor and coil in older vehicles. A bad coil pack can cause various symptoms, such as stalling, failure to start, and strange engine sounds. If you suspect a problem with your coil pack, it is recommended to use an OBDII scanner to pull trouble codes and narrow down the issue. You can also visit a local parts store or an Advance Auto Parts location to find the right ignition coil for your Impala.

Signs Of Bad Spark Plugs
Worn/failed spark plugs, coil packs, or spark plug wires can trigger your check engine light to come on. In today’s cars, if a spark plug fails and can no longer ignite the air-fuel mixture, then the most obvious event should be the check engine light coming on or even flashing.
Do cars have both spark plugs and coil packs?
On a modern car, coils typically are mounted directly on top of the spark plugs, so the high voltage does not have far to travel. Others mount boxy coil packs to the fender, firewall, or motor, with short leads to the spark plugs.
Can u drive a car with a bad coil pack?
If you know for a FACT that the coil packs are bad, replace them! If it’s speculation based on an online guess, or parts counter guess, hold off. Bottom line, if it’s a misfire with a flashing Check Engine light, you are damaging the expensive catalytic converter by continued driving.
Will bad coil packs throw a code?
Yes, a bad coil will definitely cause a check engine light. Typically, if it is just one going bad, the DTC (Diagnostic Trouble Code – the code that causes the light to come on – which can be read usually for free at most auto parts stores) will correspond to the cylinder that has the bad coil.
Do all vehicles have coil packs?
All automotive ignition systems (except diesels) have to generate a spark strong enough to jump across the spark plug’s gap. This is accomplished using an ignition coil consisting of two coils of wire wrapped around an iron core.
Should I replace all ignition coils or just the bad one?
Do ignition coils usually go bad one at a time or all at once? Change all after reaching a certain mileage. Coil packs are reliable and likely to last the lifetime of a vehicle. If anyone goes bad, there is no need to change all of them.
