Runs rough and tapping, then it starts running normally?

Hi,

That is a new one for me. By chance is the check engine light staying on or flashing while the engine is running? Also, has the oil pressure light ever turned on while this happens?

Let me know. Also, if you had the computer scanned, let me know what codes were found. If not and the check engine light is staying on or flashing, have it done. Most parts stores will do it free of charge and let me know what you find.

Let me know what you find.

Hi,

If the check engine light is flashing, that indicates a cylinder misfire. What code did you get for the MAF? Also, are you sure there are no other codes stored?

Also, when you hear the noise and it starts running poorly, does the oil pressure gauge drop?

If it is possible, could you record what you are hearing? The idea that the check engine light flashes when this happens and it indicates a misfire, which would explain the poor running. If the oil pressure gauge doesn't drop off, we may be dealing with something totally different than an internal engine issue.

Let me know as much as you can.
