Need to complete the tuneup.. Here read this post (1998 and up 5.9L and 5.2L)
Also may need to clean your throttle body; cleaning the throtle body is really not difficult. All you need are some simple hand tools, a can of carb and choke cleaner, and a new gasket. Simply remove the throttle body and generously spray it down with the cleaner and use a stiff bristle brush to remove the heavy carbon deposits and reinstall. As for flushing the injector system, CRC makes a great product that you simply add to the fuel tank at your next fill up. So for about $25 and an hour of your time the job is done.
How to clean your Throttle Body: Most people think that cleaning the throttle body requires a can of Carb/Throttle Body Cleaner and a quick "wash" of the bores. This may work, but only washes the dirt and cleaner down into your intake manifold where it can puddle up and break down the belly-pan gasket. Then, it also is pulled into the combustion chamber where is can foul up the spark plugs.
The proper way to clean your throttle body is to remove it from the engine (you'll need a small pan, some compressed air, and a new throttle body gasket for this procedure):
1. Remove your air hat from the throttle body
2. Disconnect the sensor connectors (TPS, MAP, and IAC)
3. Remove the four throttle body bolts
4. Lift the throttle body up and away from the intake manifold (place a rag over the manifold opening to prevent anything from falling inside)
5. Remove the three sensors (Do not drop them)
6. Remove the three screws for the throttle linkage (Not required...can be done with linkage attached)
7. Place the throttle body in a small pan and spray Carb/Throttle Body Cleaner in the bores, underside passages, and ports. Let soak for about a minute.
8. Spray some more Carb/Throttle Body Cleaner in the bores and ports of the throttle body
9. Wipe clean with a lint free rag (baby diaper works well) and blow out all the ports with some compressed air (a small can from a electronics store works just fine).
10. Reinstall all sensors, then reinstall on your vehicle with a new Throttle Body gasket (don't forget to remove the rag)
11. Reset the computer:
How to Clean the IAC Solenoid:: This is recommended at every Tune-Up to prevent excess carbon buildup on the IAC plunger. In some cases, you'll notice a slightly erratic idle quality. This is the first step in taking care of that problem. IAC = Intake Air Control (Solenoid).
1. Remove the Air Hat from the Throttle Body
2. Disconnect the sensor harness from the IAC Solenoid (Rear of Throttle Body)
3. Remove the two Torx-25 Screws
4. Remove the IAC Solenoid (Be careful not to lose the rubber O-Ring)
5. Spray some Carb/TB Cleaner in the IAC port on the Throttle Body and let it sit
6. Spray some Carb/TB Cleaner on the tip of the IAC Solenoid and wipe clean (Do NOT forcefully twist or push the plunger - You will damage the Solenoid. Wipe very gently.)
7. Spray a little bit more Carb/TB Cleaner in the IAC port on the Throttle Body and wipe clean with a thin/lint-free rag
8. Reinstall the IAC Solenoid (Make sure you don't lose the rubber gasket on the solenoid)
9. Reinstall the sensor connector and airhat
10. Reset the computer:

Hope this helps.

On the back of the ignition switch is a electrical switch ,at the end of the lock barrel ,change this as i think it may have dirty contacts which will cause the exact symptoms you describe
