Default Low Idle

hey guys
First i have a year 2000. I'm having a idle problem. When im in neutral and rev just a little and then let go, my idle goes down below 500. It goes to like 1 bar color then my car shakes like is about to die and then it goes back to normal like revs back to 1100 then it drops to like 700 or 800. The car never died, but every time i rev it does it over and over. Not sure what to do. any points?

thanks

I have the same problem on my 01.

sometimes when you step on the throttle 10-20% from a start, the car feels to bog, not really get any power, until you step on it some more.

I searched around and a few people seemed to have fixed their problem by cleaning the MAP sensor, as well as the little intake hole (to the map sensor) in the throttle body.

Added, on top of that, try a ecu reset with the fuse removal technique.

Do I sound roughly on the ball?

Well i was in neutral and rev it and then it drop down to 1 bar color and the car started to shake( feel like its about to die) and then i saw it go back up to normal like almost 1000. I will try your guys method first.
thanks you.

Had this same issue and it went away after replacing o2 sensors. It is a lot more smooth and does not drop below 750rpm, preventing that engine bog you mentioned. YMMV
