Alright so, i know that my check engine light is on and i need a MAP sensor, im pretty positive, idk if it causes my rpms to juggle or not, and my throw out bearing is going out clutch is a little worn, but its around 600-800 rpm at idle, but then when i turn the heater on it arouns 1k-1.5k idle, was wondering what would cause this, and if the map sensor could do this. thanks
