Indicates an ambient air temp sensor or BARO sensor problem
run the fault codes
the ECM tunes the engine every 60 seconds from reports for sensors so the old fashioned tune up is not longer cost effective
better to have the fault codes read on a regular basis
an occasional can of quality injector cleaner in the tank is a good investment

could be that the electronic throttle could be icing up. just remove the air cleaner and have someone cycle the key. the throttlebody will cycle prior to starting to do a self check. chrysler has a tsb out for this concern. tsb # 14-002-05
SOURCE: When is it time to tune-up a 2004 Dodge Ram 1500
30,000 mile plugs but it doesn't meen they need replacement I work for chrysler I would wait till about 50 or 60 thousand remeber just because there is not a problem doesn't meen they should not be replace at the recommened intervals. they are considered a wearable item. when you do the plug do the wires. words of advise when doing the ignition wires do ONE WIRE AT A TIME it will save u from a big headache. Good luck.

SOURCE: 1999 dodge ram 1500 5.2L timing,plug gap,firing order
You will find the spark plug gap and timing specifications listed on the vehicles emission label under the hood, and those specifications are the ones to be used on that vehicle and engine for that year, and no other specifications should ever take precedence over the specifications listed on the vehicles emission control label. Here is the firing order diagram for that engine, let me know if you require any further assistance, and I an curious as to how you got taken for $2,000.
