I have a 2001/2002 Renault Clio and for the past year have experienced problems with the ECU. Initially when slowing the car down for traffice lights, roundabouts etc the ecu light will come on and the engine would stall. I took it a local auto electrician who put it on the diagnostic test and revealed it was the idle control valve. They suggested they they clean it up and reset the ecu as 9 times out of 10 this cures the problem.
One day in the garage and £120 later i drive my car out and within 2 days I experience a similar problem. This time the car stalls and will not restart for a least 5 minutes of turning the engine over (ECU light does not come on). This is particularly annoying when it happens during rush hour in single lane traffic.
I'm not sure whether to grin and bear the cost of a new idle control valve which will set me back in excess of £400 of my student income (not knowing if this will cure the problem) or try and replace the part myself with a genuine used part.
I'm pretty good at repairing cars but need to know how do I gain access to the idle control valve ( i'm guessing it's in the air flow meter) and is it an easy job.
Just for the record since I purchased the car 4 years ago it has always idles at around 500 rpm which I think is pretty low and remains to do so. Can anyone advise??
Thanks in advance for taking the time to read this thread.
