I am assuming you mean F150 truck.
The answer is maybe.
Code 305 and 306 are missfire codes for cylinders 5 and 6.
Code 1518 is for a problem with the intake manifold runner control which could cause the other two codes.

P1518 FORD Description The Intake Manifold Runner Control (IMRC) is monitored for failure during continuous or key ON engine OFF self-test.
Possible causes - Intake Manifold Runner Control (IMRC) harness is open or shorted
- Intake Manifold Runner Control (IMRC) circuit poor electrical connection
- Faulty Intake Manifold Runner Control (IMRC) actuator

May want to purchase a Haynes or Chilton manual and study the vacuum line diagram to see if you can determine if one of the vacuum hoses is loose or misplaced or broken.

One can also do a visual inspection of the hoses to see if any are disconnected from where they should be.

oxygen sensor, vacuum leak, and yes it could most definitly be if you swaped the wires of the firing order accidently you will get a code p0171 Check the tubing going from the air filter to the intake manifold to see if it has come loose. This might account for extra air going into the intake manifold than the computer is aware of. Otherwise it may be due to a faulty(or dirty) MAP/MAF sensor. Another possible cause is from low fuel pressure due to restricted fuel lines or a bad fuel pump.
