I know there are a million of these threads out there and I can't find one with the same details. To make a long story short....

I started my car yesterday and the SES, TCS and Slip light stayed on. I unhooked the battery for 30 secs (short on time) and the Slip and TCS light went away, but the SES light was still on. I then unhooked the battery for the full night and all the lights went away. Everything seams fine now, but something set the code off. I haven't had the time to get a code pulled, so I'm posting on here first.

I have a 2k GLE, ground wires, y-pipe, optima battery... not that any of these mods matter... just thought I'd list them.

Thanks in advance

 

You right there are millions of threads on this. This combination of lights most of the times (not all) means a misfire and probably a faulty ignition coil.

 

Sounds like a coil to me.
