do you have that rubber thing under the map sensor? i also know some kits give you this thing put under you map sensor and it causes the kit to sit much higher.

if you look on the stick of motor pics in the forum look at nutsacks motor picture, and you'll see what i'm talking about for the map sensor.

when we pulled my friends map sensor off, we accidently left the rubber piece off, and it burnt half a tank full of gas in one day.

also we had played with the tps sensor (overbord tb), and it wasn't set back to spec. I dunno how much the map sensor effects the idle...
