1999 1.8T Passat and OBD codes

[mjones95]

about 4 days ago my engine light came on as i pulled up to a stop light. The car wasn't shaking and there wasn't any noticeable loss of power. However, since then, the car is burning gas extremely fast.

i was able to get OBD codes:
- P1136 "Long Term Fuel Trim Add.Fuel,Bank1 System too Lean"
- P0303 "Misfire in Cylinder #3"

From what i have been able to gather from info online (and it's been really tough to find) it seems like the car needs more fuel to the engine (ie. a new fuel pump) and/or a tune up, which was recommended by the person i spoke to at the car shop.

My questions are:

A: Does anyone have experience with these codes? If so, what did you do?

B: If i need to replace the Fuel Pump, how hard of a job is that?

C: Are there any simple solutions?

Thanks in advance.
