Car Will Idle Up And Down

[hondarama]

WHen i start my car in the mornin it will idle fine then it will start to idle up and down then it will idle smooth when gettin goin. wut is that problem?where can synchros be purchased? How can you get to the back of your gauge cluster?? im confused bout a lot sooo um can i receive some help and i appreciate it.

Whoaaaaaaaaa buddy, slow down. There's nothing wrong with your gauge, the syncrhos are in the transmission and have nothing to do with this. Since the problem only happens when the car is cold, my guess is the fast idle thermo valve, which controls the warm up idle and is on the throttle body. There should be a little port coming off the throttle body, this goes to the fast idle thermo valve.

Since yours is after warm up, definitely check the IACV, and check for vacuum leaks.
