A Ford Focus had an engine misfire.

The check engine light was on and the car would hesitate when accelerating. There were codes for a misfire on cylinder 1 and a misfire on start up.

We swapped the ignition coils on cylinders 1 and 2, and the misfire moved to cylinder 2.

The ignition coils, spark plugs and valve cover gasket were replaced.

If your car isn’t performing like it usually does, it could be the victim of an engine misfire.

When a vehicle doesn’t have the correct amount of air and fuel, it can result in a misfire.

Some misfire symptoms include a car running rough or struggling to accelerate. You might notice the check engine light turn on, too.

Many culprits can lie behind engine misfires.

To name a few possibilities, there could be something wrong with a valve, a sensor problem, or parts that have become worn out.

The reason may not be discovered through a visual inspection. Sometimes, a little detective work is needed to find the cause.

Cylinder 6 has no compression.

P0300 Random Misfire: Causes, Symptoms, Fix

The P0300 random misfire code is one of the most common engine trouble codes found in modern vehicles. When this code appears, it means the engine control unit (ECU) has detected multiple cylinder misfires occurring randomly rather than in a single cylinder. Unlike codes such as P0301 or P0302, which indicate misfires in specific cylinders, the P0300 code signals a broader engine combustion…

As in the case of cooking, cars require the correct mix of “ingredients” and circumstances to work properly.

For example, it’s important that the fuel and air levels in a vehicle are right – that they don’t lack or exceed what’s necessary. If they do, it could result in an engine misfire.

Misfires impact how an engine runs. If left unresolved, they can eventually cause damage to components, including the catalytic converter.

A catalytic converter may melt if the exhaust contains raw fuel or a lot of fuel.

We have suggested spark plug replacement and ignition coil replacement on an Audi A3.

There was a code for P0302 cylinder 2 misfire. The technician switched the spark plugs and ignition coils on cylinder 1 and 2 before taking the car for a test drive.

He found that the engine misfire moved from cylinder 2 to cylinder 1. The maintenance schedule for this vehicle says the ignition coils should be changed every 40,000 miles. It has more than 95,000 miles on it.

New ignition coils and spark plugs are needed on a Toyota Tacoma.

The pickup truck had an engine misfire on cylinder 1. When we moved the ignition coil to cylinder 4, the misfire code disappeared.

Misfires can also be the result of engine problems as well as bad fuel injectors or timing belts. 

Choosing to ignore misfires can cause the problem to get worse.
