engine idle

[richd]

my car is idleing at only 750rpm when the engine is warm, when cold its between 1200-1500 rpm, not a huge issue but once warm it idle's abit lumpy, is there an easy way of adjusing it?

There is no adjustment... It will be a faulty sensor causing it. You could try servicing the TB or replacing Lamdas and CTS but I'd recommend a proper check using the live data.

not getting no lights on the dash tho, it drives fine with no issues just wonderd if anyone else had had the same issue and had an idea what it could be but thanks, ill look into having it checked

Faulty sensors rarely throw up lights, they just give the ECU incorrect readings which it uses to make decisions about how to run the engine.

can this then effect performance and fuel consumption?

 

[MicKPM]

Yes, very much so!

That explains things for me too!

My fuel consumption is very poor for the driving I do.

And it idles at 1200-1300 cold and 750-800 ish when it's warm.

It does feel lumpy/laboured when it's idling warm.

What sensors we talking about then?
Much of a job?
