I have several codes; P0171, P0174, P0300, P0303, P0308 P0316, P2195 P2196, P2197, P2198 and P0506. The car takes a while to warm up and it shakes misfire and sometimes I can push the gas pedal all the way down and it does not move then all of a sudden it takes off. It drives fine once it is warm but it feels like it will stall at stops. I got reading that said replace PCV valve and hose, but my car does not have one. What part is similar to this part or can cause these symptoms? Where do I begin or repair first?

You have a bunch of different codes there. first thing is to check battery for condition including load test. also, check battery terminal ends for cleanliness. then check fuel pressure and for a vacuum leak like a hose off that will be a start. See link.
