Little more info please. What year, model, engine, tranny? Done any work to it recently? Happens all of the time or only cold, hot? Did you just fill up with a fresh tank of gas and then this started happening? With the codes you posted, I would think you have an OBD I rig, but then you should have pulled a 55 also.
I have to go to work now, but maybe someone else can point you in the right direction.

Check your CPS (crank position sensor)
Also check for vacum leaks.
