PUG 306 Nearly Stalling - thalamus89
My 1997 306 2.0 8V XSi is having troubling idling from cold start up. It won't stall but it idles at about 400-750 and it is struggling. Now this is only happening at night with full lights on, stereo, heating etc. During day it's fine.

Recently I have had the lambda sensor replaced as it was knackered and causing it to stall regularly. Before replacing the lambda sensor, it has also had a new stepper motor and engine coolant sensor.

Any ideas or advice very welcome.
