PLEASE HELP!! loss of power during acceleration and intermittent rough idle

I stand corrected. I looked at the list of the codes. The one I previously listed as p0100 was actually p1000 so I guess the mass air flow sensor doesn't have any issues

That's good. The P1000 is just a drive cycle code. One less thing to worry about.

I'm beginning to think I have a blown head gasket too

Update: put it in the shop. Warranty covered replacement coil packs for cylinder 2 and 3. A vacuum hose was blown in half. So that's what set off the codes p0171 and p0174. Been driving great. Now I'm having another misfire. Cylinder 4 p0304 and p0305 cylinder 5. I replaced coil for cylinder 5 myself before I had them replace 2 and 3. And it did the same thing. Ran good. Then started again and threw up the codes for cylinder 2 and 3. What could cause this?!?! If one goes out do they all start to? Or what. please help
