P0305 and P0014 can one afect the other and how to fix

PO305 is cylinder #5 misfire.
PO014 is Camshaft position fault.
The camshaft determines which valves open and when. If the cam is out of position (called "jumped timing"), several bad things can happen. Usually an engine that has jumped time will not start or will run very roughly with little to no power if it does start.
Chances of jumped timing are low, but in a high-mileage engine, not impossible. More likely is a faulty cam position sensor or wiring. Misfiring of one or more cylinders is quite likely in this condition.
Additionally, once the cause has been corrected and the computer codes reset and cleared, you may very well get an emissions error code, as actual cylinder misfiring (even running out of gas) is notorious for causing emission control, catalytic converter and O2 sensor failures (any code between PO400-PO499).

This is a fault in the fan speed sensor circuit. You may need to check the connector or replace this sensor. Remember to have someone clear the computer. Some defects will clear automatically and others need time or a scanner to clear.

My cruise control does not work

Normally when this happens, your computer has a stored or active check engine light code. If there is a code present, your computer will disable the cruise control feature until the check engine light or code is cleared.
