It could be several things but most of the time with these its a faulty EGR valve that causes the off idle sputter. You can take a piece of tin soda can and bolt it between the valve and intake. If the probelm goes away then the EGR valve is at fault.

Not picking up gas when engine is cold, sputtering, bogging out especially when travelling uphill, Is this some sort of a sensor maybe??,the spark plugs are new. thanks


check fuel filter. it is starving for fuel. unless the fuel pump is bad. check filter first, then go from there. symtoms of a bad coolant sensor--poor cold idle, stalling, rich mixture retarded timing, slow idle speed, cold hesitation or stumble, poor fuel milage.
