This can lead to incomplete combustion and result in poor performance as well as increased emissions from the exhaust system. Faulty Spark Plugs: Spark plugs are responsible for igniting the air-fuel mixture inside your engines cylinders, and if they become worn out or faulty, they can cause sputtering when you accelerate. To find out if your engine has low compression, you need to do a compression test and compare the results to the manufacturers specifications.

Here is a more detailed list of how to diagnose and fix engine misfires: Modern car engines have a system that monitors all the sensors in the car engine, and if there is something wrong with a sensor, it will store it as a trouble code in the engine control module. The X is replaced with the cylinder number where the cylinder misfire occurs; for example P0301 is a cylinder 1 misfire. About 3 months ago my Mustang starting sputtering and backfiring on acceleration pretty bad. You seem to have the first 3 covered so whip the top cover off and check the line to the coil had not become a mousy teething ring and a bit harder the exhaust has not become bug Hilton.

Exhaust Manifold Leak - The exhaust manifold traditionally funnels spent exhaust gas from the engine. Finally, poor fuel quality can also have an adverse effect on overall vehicle efficiency as more gasoline needs to be used for sufficient energy production during acceleration periods; this leads directly towards decreased mileage per gallon figures as more gasoline needs to be consumed than would otherwise be necessary with higher-quality fuels being used instead. Vacuum leaks are a common cause of an incorrect air-fuel mixture and are fairly easy to check, so you want to start there. However, plugs wear out and can no longer function as intended.
