It could all be related.P1537/38 are the intake manifold runner controls are stuck open.They are controlled by vacuum solenoids.The P0171 is bank one of the engine is running lean,usually caused by a vacuum leak, P0420 is catalytic converter efficiency code. The computer monitors the switch rate of the front 02 sensors and compares it to the switch rate of the rear 02 sensors to tell if catalytic converter is doing its job. Now if the front 02 is not switching properly then this will cause this test to fail and set this code.
Look on bottom section of the intake manifold at the back of engine(where tranny bolts up) you should see the vacuum motors there on the intake,these are the control motors for the intake manifold runners.Make sure the vacuum lines are hooked up and lines are not leaking. Also you will see a lever from it to intake make sure they move and are not binding.

I have the same issue, but mine got a little worse as time went on. I got a new motor for and when I took the door apart I had to lower the window. so I had to plug the switches back in, and what do you know it started working. so I tested for 15 mins stiaght and it statred working every time I pushed the button. So, I would try that first before you spend over $70 dollars just for the part.
