Hello, thank you for writing in. Unfortunately, there are a large number of components that can cause this. The vehicle needs to be scanned for diagnostic codes. Even without an engine light on, there may be code present pertaining to an issue the computer is detecting. If there are no codes to work with, you will want to look into the basics. Start with testing for proper fuel pressure, spark timing and voltage, crankshaft sensors, compression, and timing. For more help with this testing and diagnostic work, contact our service department to schedule an appointment.
