View Full Version : Mystery SES light...

Well the SES ghost is haunting me.

The light comes on and its throwing random misfire codes.

its not fuel sys as i had a new one put in in november by a dealership. There is some slight stutter rarely when accelerating from a stop... but only like 10% of the time. if that...

If i reset the pcm it will go away for a few days then come back **only when my wife drives it**.

Only lead i have is that the light came on after i cleaned/re-oiled my K&N filter. Dirty MAF perhaps?

Any help is appreciated thanks!

You possibly over oiled your filter. The excess oil would get on the MAF. Try cleaning the MAF and wiping off the excess oil off your filter. Also, hook up a scanner to read what code is causing the SES.
