Hi all, I have a s50 M coupe, I have an intermittent idle issue once warm, from cold start its idle is pretty steady around 650, however from a restart the idle can sometimes die, but before it does it might bounce up and down a bit, but again this is intermittent.
The car is running better and better the more I use it and have run injector cleaner through which helped, goes really well and doesnt seem to struggle with low down torque.
I havnt looked at idle control valve or breather hoses yet, but thought before I do what sort of information can be gained from a full diagnostic scan? Would it tell me if an o2 sensor or something else along those lines is faulty. I have had it scanned but looking at the paper work it was a quick scan and showed no faults other than a few relating to perhaps having a flat battery.
If it was an air leak I would have thought it would be a constant idle issue, but as its from a restart and hence at this point using the onboard sensors to inform the ecu whats going on, it could well be a sensor, and hence a full scan could show this up.
Would the idle control valve lead to a fluctuating idle from cold?
If anyone could recommend someone who could carry out a full scan somewhere close to Nottingham would be appreciated. Thanks guys, Dave
