When my tuck is idleing it idles at about 900RPM and say i rev it up a lil bit it does not matter how much. When it revs back down it drops to about 300 to 400RPM and about dies then shoots right back up to normal,,I do not kno it a sensor could be bad and which one or if it just needs a tune up or what.

Try this clean out the idle air control valve and if it continues test the MAF, MAP and TPS sensors
