Could be that you fried a O2 sensor. All that carbon and smoke can't be good for a older O2 that was on its way out would be my guess.┌∩┐(◕_◕)┌∩┐

Where did you add it? How much did you use?
Have the code scanned and post it up. Chances are its one of your rear 02 sensors, depending on how much you added to the intake, Picked up something it didnt like, after having it read post it up or disconnect the battery to reset the light.Most places that scan the codes wont delete them for ya. Depending on the mileage and condition of the engine i usualy sea foam, Then after about 20 miles i change the oil and filter and replace the plugs...

I just used a half can and put it in via the brake booster vacume line.
Wound up got busy and hope to go get it scanned tomorrow and I will let you guys know.
If it is the O2 I am gonna take it to dealer I bought it from cause I got a 3 yr 36k extended warranty from them.
Have it replaced and new window motor put in on driver's side cause when temps get below 40 it will not move at all till weather warms up.

Might just be a misfire code from when you injected the seafoam.

I disconnected the batt for about 20 mins and the SES light is still on.
Ordered a reader from ebay so no more taking it anywhere.

Buddy brought his reader over today after I ordered mine and it was a random cylinder misfire.
Cleared it and no more SES.
