Default Trouble Code Help

I've gotten a few CEL's in the past 3 weeks and don't know what to do about the codes I've found. Can anyone help?
3 Faults Found:
17965 - Charge Pressure Control: Positive Deviation
P1557 - 35-10 - - - Intermittent
17521 - Oxygen (Lambda) Sensor: B1 S1: Internal Resistance too High
P1113 - 35-10 - - - Intermittent
17544 - Fuel Trim: Bank 1 (Add): System too Lean
P1136 - 35-00 - -
I'm thinking maybe vacuum leak but don't know.

That particular code (17544) has come up 3 times, if it's not visibly torn, what's a good way to check it?
