crank position sensor was going to be my first guess as well - since I had the same problem - & replacing the sensor helped/fixed the problem - but in my case it DID throw the code 'crank position sensor'...
maybe you wanna change the cam & the crank position sensors just in case - they are not too expensive but it will eliminate a lot of guessing.
I'm still voting for the MAF issue, though...
good luck.
