Hi,

On my Large Turbo Esc Cos i have a problem on idling

It idles on about 1500rpm once warmed up

Idles perfect when first started for the first 5 minutes and then it starts to happen again

Ive changed the Idle speed control valve for another one but no change

Can anyone help me as its driving me mad

Thanks in advance
Chris.

 

I've had a similar problem with my 3dr.
Changed the ISCV, but cannot get it to idle at cold and warm correctly, can set it for one or the other. I've recently been told that my ISCV isn't working, so there is something wrong with the controlling parameters.
I've checked for these so far, and should be..don't quote me on these:
Power 12v to the black/red ISCV wire.
Resistance between one of ISCV wires, and a relay in fuse box (7ohms).
TPS setting/setup i believe can impact on ISCV performance.
Relay or resistor or something in the ECU can burnout stopping it from working.

I'm no expert and haven't sorted mine yet but beleave these are places to look at, provided Es cos is similar.

 

Cheers
I think it might be a trip on the computer

Check the ECT sensor, if this is faulty it can cause idling problems.
