Hi there folks, a couple of problems doing my napper in. When pressing the accelerator pedal after i've been sat in traffick at idle for a few minutes the engine go's to max revs then cuts out. It happens all the time, hot, cold, early or late in a journey.

Quite a common one this but i'm still struggling. Heater blowing luke warm air causing problems de-misting the windscreen. I'm led to believe it could be the Heater control valve which is located on the bulkhead...where exactly and what am i looking for. I've flushed, bled, changed the stat etc.

Thanks.
