1995 Dodge Ram V8 Four Wheel Drive Automatic
----------------------------------------------------------------
After the truck has been sitting for a day it cranks ok and starts to pop then I put the throttle to the floor and it starts to run and then I work the throttle and the problem goes away. Im not sure if this is related but when driving at 30mph holding the throttle study the engine rpm surges. Also when decelerating and letting of the gas the rpm drops very low just about shuts off then suddenly catches it self. I have tried replacing the idle air control motor, cleaned the throttle body, and swaped out all the sensors on the throttle body. Please help

Have you checked the fuel pressure?
IF so is it in spec?

If you cycle the key after the long set several times will it start right up then?
