first u have to ask yourself what type of maintenance have u done via fuel filter ect,,get presure on rail check if it does not read right check regulator if you here an irreguler humm from your fuel pump will usually give you warnnin it is going out with change of this filter. I recomend!!!change the regulator with this repair.

this may be your iac unit. go to auto zone have them hook up a scanner and read your computer codes, this will tell you where to start looking.

I doubt very much this is electrical. Rather do a visual inspection for vacuum pipes that are leaking or have become dislodged especially around the throttle body(Where the throttle cable is connected to) and plenumb chamber. If you find a place that looks like a pipe needs to be connected there, hold it closed with your finger and see if the revs pick up slightly. If it does then look for the pipe that needs to go there. You shouldnt have any pipes hanging loose around the engine bay. If you dont find anything on the engine itself follow every little pipe to where it goes/connects to and do the same. This costs nothing and a mechanic will charge you an hours' worth of labour for doing the same. The engine's fuel/air mixture is being leaned out somewhere. You can perhaps have the CO content tested to confirm, as this is relatively inexpensive.

It sounds to me like you have an idle issue. Check for replacement of the I.A.C [idle air control] I hope that this helps.
