Got P300, P301 P303 codes

[JayG]

Was driving along, stopped at a traffic light and all of a sudden it started idling a little rough and the CEL started to flash and the computer said to drive slowly to service

Started to drive and after about 100 feet, the light went out and the engine was smooth again.

I was about 1 mile to my home, drove home and plugged in my durametric

There were 3 codes


This is the first time I have gotten ANY codes

I did a weekend at the track a week ago and all was good

I have 74k on the clock,. Plugs were changed at 60k Just did an oil change before i went to the track. All the oil changes (4)I have done since i bought the car in March 14 have been good

Any thoughts????
