issue 1-leak. so i know i have an exhaust leak, and its from the manifold(s)..should i put stock manifolds back on or should i just get some headers? and does anyone have any stock manifolds

issue 2-misfire. dont know if its just one cylinder or a random misfire. when you open the hood you can smell gas, so i think it may be the injectors. so should i just put in new injectors, plugs, wires, coil pack and such? the car is due for a tune up anyway, and since i dont know too much about 4th gens, how hard is it to do all of this stuff. these are pretty much the only mechanical problems with it.

btw this is a 3.4L high mileage A4 all stock i think
