How long from a cold start would you expect your zed to take to reach a normal idle of say 750/800rpm????

 

Also, would you expect this to happen before she's up to full temp??

cant say my zeds have ever gone over a min to come off fast idle and normaly idle at the above even before the temp needle starts to move upwards

Mmmmm, That's my thought also.

My rpm seems tied to the engine temperature! It only returns to an acceptable rpm of say 750rpm when the engine is above 75 degrees!!

The gauges are almost in sync with one another.

idle is a proper pita on these cars :rant:

well ide be changing the temp sensor then (bigger of the two) on left which sends temp info to ecu.

that sounds about right to be honest, the air regulator opens under cold start conditions, the thermostat on the front of the engine also stays shut until the engine comes up to 76.5 degree's C (stock) the air regulator should then close off slightly to allow the Idle air control unit to take over the idle. the thermostat on the front of the engine will open to allow coolant through to the rad. at this point the car is regulating its own temp.

 

You could have a sticking or dirty Air regulator, im sure mine comes off high idle once its up to around 40 / 50 degree's but depending on ambient out side temp, could take a while
