C20 let stalls

[Gsimad]

When stopping at lights or junctions the car stalls. It starts first time after this has happened.

I have changed the rotor arm, cap, all boost pipes and cleaned the idle control valve. But i still have this problem when car is hot or cold. Also it travelling at 70mph and put clutch down the revs drop but dont stop at idle it stalls.

Would a faulty Lambda probe cause this by flooding the engine in a way to cause it to stall.

Any info or comments welcome.

Did you check all intake system from air filter to mainfold? Maybe he have "false" air in intake?
Other thing...temp sensor for ECU...maybe it makes wrong singnals?

Stalling

The problem in the end was the one way valve between the inlet manifold (throttle body) and the rocker cover breather. Ok now!!!
