Hello when I start my 93 lumina it run at higer rpms in park or neutral when I go to put it in reverse or drive and it drops down to lower rpms it will die. It will only start back up if I am on the gas. Then I have to stay on the gas to keep it goin the second I let off it will die again. Could you please tell me what most likely is my problem I was thinkin a fuel filter but I changed it about 10 months ago.

If your saying, it runs ok off idle, but won't idle, my first thought is the idle air system.

You might check for codes. You should be able to check them yourself, use a jumper between the A & B terminals of the data link connector, turn the key on, no crank, Watch the mil, count the flashes to get the codes.
