Sputtering at Idle Every 10-30 Seconds.

mercredi 11 mars 2015

My RX8 has been sputtering at idle for awhile now. It has new coils(bhr), plugs, air filter, clean ESS with reset maps, seafoamed, Catback, grouding kit. Fluids all flushed.

Had a compression test done a couple months ago, compression is good.

The rpms will dip just a tad when it sputters. And the sputter is pretty loud. With the hood up you can hear it from 10-15 feet away. Just sounds like a little popping sputtering noise.



I had a check engine light awhile ago, I wish I remembered the code but I lost the paper I wrote it on, it was like low circuit B or something, I think it was the air pump when I looked it up. But the code went away on its own.



I tried disconnecting the MAF sensor and letting it run on defaults and it still sputters so it's not that.



Any ideas here?

Thanks



edit: It sounds like the sputtering noise in this video if you skip to 14 seconds
