Dirty Fuel Injectors
All fuel injectors on fuel injected engines eventually get dirty. Your engine has several fuel injectors that must all disperse fuel into the engine evenly for optimal performance. Therefore, one clogged nozzle can adversely affect engine performance and cause your engine to stutter.
If your car’s stuttering problem is only intermittent, it may be an electrical problem. Electrical problems can be caused by crimp joints in wiring, connectors, soldered joints on circuit boards or relay contacts.Engine connectors can get eroded, and fuel pump connectors can get very dirty causing your vehicle to stutter randomly.
Faulty Throttle Sensor
Your vehicle’s stuttering problem could also be caused by a faulty throttle sensor. When the gas pedal is pushed, the malfunctioning sensor does not send information to your engine’s computer accurately. If your throttle sensor is failing, other symptoms can include hard starts, rough idles and poor fuel economy.
A stuttering engine can have many causes, so it’s best to get your engine evaluated by a professional and trusted mechanic. For more information about other vehicle issues, including brakes, suspension or getting a wheel alignment in La Jolla, visit this site.
