Could be many things. Leaky injectors. Vacuum leak. I would need to run diagnostics and get more info to narrow it down. See our FAQ for more misfire background.

For some reason, your browser is generating several duplicates when you submitted your post. (You accidentally posted this topic six times.)

Are you having network issues? If so, then please wait until you have a stable connection. If you are pressing the submit button more than once, please stop. Press it once, and wait for it to finish processing. (You will find in most cases if you return to the topic list your post was processed immediately even if the site appeared unresponsive.) Otherwise it creates more work for moderators to clean up, and eventually the system will automatically ban your from entering. Thank you.
