Loss of power below 2000rpm 7afe

[Timmo617]

Hi I have a 2000 AE112 Corolla that's having problems with acceleration. On cold start up it sits below 500rpm for few seconds and almost stalls. Then it goes to normal idle rpm. When I drive the car, it has hardly any power until it hits 2000rpm. I flat foot it and hardly moves and jumps like it wants to go more but can't. After 2000rpm everything works fine. I cleaned carbon buildup from inside the throttle body and it didn't change anything. Does anyone else have any ideas what I should be fixing?

I would be looking at cleaning the IAC [idle air control valve] particularly as you have mentioned carbon buildup inside the throttle body.

This is one YouTube video on the topic.
