In the morning when I start my car it will rev up then putt out and die, normally the second time it will stay running but it will rev up then real low like 300 rpm then back up and then it will keep reving between 500-1000 for a min then it will run fine.. and when i've been driving it at like lights ill have my foot on the brake then it will try to lunge forward a bit. Also when I'm driving it seems to be catching when I let off the gas which it shouldn't do, its an automatic.. my friend said it sounds like the torque converter.. what do you guys think.

 

could just be a vaccum leak spray ether on all ur intake parts...
