    THis has been happening for like months now. Whenever my car is warm, and i come to a stop, the idle drops, then comes back up, then drops, as if the car wants to die. IF im in park or neutral and i rev, the motor does the same thing. COuple times the car has died, and in traffic too! So far i have cleaned the IAC, replaced the TPS, cleaned inside the throttle body and plenum, seafomed the motor, and just this morning i cleaned the MAF, and its still doing it! My auto has a shift kit too, and when i shift into gear, it shifts like it normally should, but it feels like it wants to die sometimes. Im going crazy! Any idea what it could be? thanks!

    maybe the IAC is beyond cleaning and needs to be replaced...your symptoms are what mine were before i swapped my IAC and it fixed it.
