High speed performance is good. When driving in traffic or stopped, all of a sudden engine lights go on and excelleration is poor at best. I stop the car shut off the motor and restart and then its fine again. In a day or two the engine light recycles and goes off. This is a happening frequently. Car bucks alot also. Thanks.

 

Sounds like either the APP (Accelerator Pedal Position) sensor, which is a fairly common complaint on these boards, or a restricted EGR valve.
Since the CEL did activate, you can have your mechanic or Advanced Auto scan the OBDII for the codes, which will tell the likely cause.
