P1506 Manufacture Control Vehicle Speed Control
P1131 Fuel Air Metering
P1151 Fuel Air Metering
PO171 System to Lean Bank 1
PO174 System to Lean Bank 2
PO303 Cylinder 3 Misfire
PO304 Cylinder 4 Misfire
My question is where do I begin? I was planning on putting in a new Coil, wire and plugs, but do not want to do this till I figure out why it is running lean, because I would hate to foul out the plugs.
Any help and suggestions would be much appreciated.

Vulcan or Duratec Engine??? P1506 is Idle Air Control Overspeed Error.
P1131 is Lack of Heated O2 Sensor 1/1 Switch, Sensor Indicates Lean.
P1151 is Lack of Heated O2 Sensor 2/1 Switch, Sensor Indicates Lean.
P0171 is Bank 1 Fuel System Lean. P0174 is Bank 2 Fuel System Lean. The misfire codes are correct. I'd be looking for a major vacuum leak right about now. If a Duratec the intake manifold gaskets are known for leakage. look for and fix the vacuum leak before chasing a misfire. The vacuum leak MAY be causing it to misfire.
