Hi guys, I searched the forum everywhere but I can't seem to find one that replicates what is happening on my car.

I have a 2005 MC, recently got set of 17" web spokes with new tires and a K&N drop-in air filter. Those are the only things changed to the car.

Whenever I drive on the freeway my car throws a SES light followed by a DSC light. The car runs fine, no loss of power or anything, just the annoying set of lights. When I restart the car I lose the DSC light, but the SES light stays. It would disappear once I'm driving around city speeds then pop-up again once I'm on the freeway. Any help is welcome, I'm trying to avoid going to the dealer as I'm struggling on college itself. Any ideas?

Thanks.

 

Try pulling the codes using the "secret" menu.

 

Just checked, nothing came up.

Looks like I'll have to spend some money, I'm OCD when it comes to error lights

 

ABS light on at all? I know I would sometimes not get the whole trifecta. All went away when I replaced the drivers side speed sensor in the knuckle.

 

I will check that, it may be an effect from upgrading my wheels from the 16" to 17"?

 

I was thinking the ABS light should come on as well if this is the case since the DSC and ABS use the same wheel speed sensors...and no codes even though theres an SES light? Thats strange.

 

I took it to a shop to check the codes, turns out there's a misfire. I didn't do the $95 diagnostic they were asking so I don't know the culprit.

I'm kind of puzzled, my car runs the same as before but there's a misfire? On my way to the shop I noticed that driving over 75mph throws the SES light.

Any ideas?

 

Sorry I dont think I can help with that. I havent had any experiences with an SES light at all actually
