Idle

[Willbee]

After having my engine fully rebuilt it is sounding sweeeeet. Just got a little issue to sort though..

When at idle it's running a little lumpy and then it wants to stay at around 1500rpm when off the throttle until the car has completely stopped when it then reverts back to around 1k and lumpy again. Does this sound like a sensor issue perhaps?

And to add, also it's lumpy when feathering the throttle...

[Willbee]

Anyone got any ideas?

can you get a vid? there a numerous issue's this could be as far as i'm aware..

from sensors as u thought, ICV, Vacuum leak, timing out..

Have u managed to check anything?

It's the long list of usual suspects for idle issues I'm afraid

Lambda, coolant temp sensor, speedo cable earth, idle control valve, TPS or the wiring connections to all of those that are possible causes

And let's not forget crank sensor.

Hmmmm that's debateable that just usually means the bloody thing wont start

This is true if it is ****ed totally, but if there is metallic debris it can throw off the 'hall effect' pulses to the sensor and cause some issue, sometimes.

Oh, and you spelt debatable incorrectly, young man. And yes, tonight I am the spelling police :D
