WHEN STOPPED, OCCASIONALLY REVS DROPPED AND THEN RAISE BACK UP. DOES ONLY WHEN STOPPED, I BELIEVE IT COULD BE THE FUEL PUMP, OR MAYBE INJECTORS.

my car will suddenly drop revs when I stop and then gain them back a few seconds later. Only happens when stopped, and then goes back to being normal. Its a manual and it sounds similar to when your about to kill it ya'know. Does it regardless of having a full tank of gas or near empty. Any advice is greatly appreciated.

car could need something like a new fuel pump I believe, though the one on my car does look new.

Check the idle air control valve, TPS and MAF sensor-if okay check the fuel pressure
