The rpm's will drop off very slowly and sometimes hold around 1500 and then drop off below 500 making the car start to bog down and sometimes die.

    looking for a place to start. My 1998 mustang V6 has backfired a couple of times in the past, and stutered off and on a few times, but just recently won't idle.
