Hello Donald
are you sure of the code
may be its p0304
which is the truck may need a tune up
or check # 4 cylinder for misfiring

Dear mr. Ken you were right the codes were p0340 I googled it and it showed a camshaft position sensor could you tell me more about this

When cranking PCM look for signals from the sensors to identify where is each cylinder and to fire
so if a signal is missing or interrupted check engine light will come on to let the driver know that there is a problem
in your case the cam sensor is the trouble area
I would start by checking it and its plug and wire
(replace cam sensor )
