Hello and thank you for trusting me with your question. My name is XXXXX XXXXX I will do my best to help you with your problem. This is usually caused by tune-up issues, so if the engine has not been tuned up for awhile it may be time, other possible causes are the ignition coils or a dirty injection system. Let me know if you have more questions on this I am always willing to help, Thanks.
