Initial Idle

[Ricardo]

Guys, what effects idle? I always allow mine to warm up (LCR) when starting from cold. So does my friend from work with an LC. When we leave work he has buggered off and I am left waiting ages before the idle speed drops from 1500 rpm to 800. It takes 5-7 minutes which I am pretty sure is excessive. If any one has ideas for things I can check, clean, kick please let me know.

May sound odd that I dont just drive off with high idle but for some reason I get a lambda fault code if I dont wait for it to drop.

Cheers

if you sit there idling for 5 mins thats why its not warming up propely, if driving it still isnt warming up, the thermostat could be stuck open.

The handbook recomends warming by gentle driving and not to let it warm up on tickover

The worry I have is that it takes a long time to settle to normal revs, I will have a hunt and try to find out more on the thermostat, cheers.

It should settle to normal revs in approx two mins from cold... my LC does...

Yeah same here, and just drive it gently.

Thanks mate thats what I was looking for. So mine does have some sort of problem. Now I just need to find out what controls the idle speed from start up and why it takes so long to drop.

 

[LEE69]

THE CTS controls it.

 

[Ricardo]

Balls, I changed that about 4 months ago, I will grab another one, thanks for the input

 

[LEE69]

Not unknown for them to go faulty.

my car only seems to idle for about a minute, i start the car, take it out the garage and then lock the garage and idle then goes off, pretty quick in mine.

Does the sensor in the coolant bottle do anything other than level?

 

[LEE69]

Yes gives you a beeping fuel light if it is dirty other than them two, no.

 

[Ricardo]

Thanks for your help, its appreciated, I think I will flush the coolant and change the sensor again, looked in my bottle and its full of little black bits which isnt good so fingers crossed.

mate, try a throttle body reset... helps settle the idle quicker, or try cleaning it then resetting.

did mine and it helped, although mine never took 7 mins, bout 3 normally, a minute now.

 

[Ricardo]

will clean on saturday + sensor into the side, then reset, cheers

 

[LEE69]

The sensor comes with a new coolant bottle not separate.

 

[james walker]

do you have acces to vagcom to reset?

 

[Ricardo]

booked in on Tuesday for flush and reset

I had this, washed the coolan bottle and i get a true fuel reading now so when i thought id run out and dashed out for fuel, it had some in.
