In the last few days my Let has been Stalling when coming up to roundabouts, junctions etc. The revs drop and the engine stalls. I am running standard chips, cleaned the idle control valve, replaced all the small hoses, checked the boost hoses and changed the one-way valve on the throttle body, the temp sensor on the throttle body and the coolant sensor.
There is no fault codes and the car runs fine apart from the stalling.
I am thinking of the breather mod and changing the idle control valve. Any more suggestions to my problem.
