Idle Issues

[Adams-Sideways]

Hi guys, having a little issue with idle at the moment. When i stat the car sometimes the idle will sit at 800 ish as it should but then go up and down very low like 5 times very uniformly? Does this sometimes at traffic lights aswell?

Any ideas?

Thanks

Will be a t shaped object, a few inches longer... One end connected in the intake boot and one end going into a pipe that goes into the left side of the throttle body

thanks mate, all the pipes connected to the throttle body are like friction fit metal pipes, should there be like some sealant there cos they pop out easily?

Thanks
