Ok i am going to try to be more specific here,
I dont really know where to start or what my problem is. I current have a idle/fuel problem. There are 2 sensors on the throttle body. One is on the top (map sensor) and one is on the side. You can unplug both of them. With everything plugged in like its suppose to be, map sensor, iacv, other thing, etc. my car surges at idle. It goes from 1k to 2k like im tapping the gas at idle. I unplugged the sensor on the side of the throttle body and now it idles high. The problem is, when i start my car; the rpms drop down to like 900 and it feels like my car is about to stall.

Im not really sure if the shaking of my car and feeling like its going to stall is beacuse of a bad part or what, but ive been dealing with this for awhile and I would really love some help. Give me what you got guys, i wana get my new civic running like it should be.

does it idle fine once the car is warmed up? if it does then your IACV is fine, if it only idles badly when your car is warming up then you should check your Fast Idle Throtle Valve? FITV n e ways that controls idle when the car is warming up and shuts off once warm
