I had problems with my civic stalling after turning it on and it running rough but I fix the stalling it stills runs a little rough it gave me code 16 (injector) but it turned out to be it was missing the clips on 2 of them so I fixed that problem but now it still runs a little rough and it tops out at low rpm's the code 16 went away but now I have a code 5 (map) sensor would the map sensor cause that and why at higher rpm's and not low?

Also replaced the icm coil cap and rotor spark plug cables valve cover gasket and grommets and also when I took the pcv valve the car seemed to run a little better but I don't know how they vacuum line go they are all messed up and I don't have a picture to go by
