Temporary burning of oil and running poor

[SuperFudge]

Ok this issue has me completely stumped; I don't even know what could cause this problem. Ok on Saturday I drove out to the local drag strip for an NMRA event which was about an hour drive and the car was driving ok, just the normal daily issues described here ( http://www.dsmtuners.com/forums/maintenance-repairs/406366-possible-bad-tps-need-help.html ). When I got to the track there was a long line so the car was idling for about 10 minutes waiting so I can pay for parking. Then I noticed that my CEL came on. So I turned off the car and did the key dance method and got codes 12, 32, and 55. When I fired the car back up the oil light came on and noticed ALOT of black smoke coming from the exhaust.

But what is strange the car no longer smokes at all.

If you guys know what could be possibly wrong with my car please let me know
Best regards,

I did this same thing once, but I accidentally let my car idle for about four hours. When I did hop back into it, it started dumping smoke like you're describing. And then it just stopped. Someone else was having this issue as well. Smokey exhaust after idling. Valve stem seals are usually the culprit.
