SES light blinking & flashing ???.... Hey guys, this past weekend my SES light was blinking & flashing for a little over 10 sec. What does this mean?.....My SES light has been on for quite sometime if that matters. Any insight?.....
That's the misfire signal, blinking SES. May or may not
relate to the always-on SES, you would have to read
the codes and dope it out. The only time I've had a
misfire problem was a plug wire that came loose at
higher than posted speeds.

K&N+ported_MAF+MAFT=anybody's guess. But that
is not something that suddenly showed up, though
it might have put things closer to the edge. I suspect
these (two of them known felons, the other perhaps
just not dialed in) have to do with the stumble. Lean
stumble, lean misfire, is just a matter of quantity and
duration.

what are the codes that are currently set? You indicated in your first post your SES light has been on if it matters... it does matter...
The blinking SES is multiple misfire detected as posted... those codes may have a link as to why it's happening (they could be bad MAF codes, bad O2 sensor codes.... )

see the stickies get the car scanned ... find out what codes it's setting ... and post them up (if you don't mind ... look them up first via the URL in the sticky .... many of us don't have all the OBDII Codes memorized yet.. and makes it easier if you post the code and description )
