Intermittent misfire

Hi,

If there is a misfire, the check engine light should flash when it is happening. Is that the case? Also, how would you best describe the sound from the exhaust?

If the check engine light flashes or stays on steady with the engine running, you will need to have the computer scanned for diagnostic codes. Here is a link that shows how it's done:

Let me know as much as you can. Since the vehicle seems to run as designed, it is possible there is something loose causing the sound you hear. If possible, record the sound and upload it for me to hear. It may be helpful.

I will watch for your reply.

Take care,

Joe
