Well.. My engine stalls.. It starts perfectly hot and cold, even after stalling it will start like a flash.. Idle runs fluently, no misfires or so.. When the engine is cold, everything is fine.. But.. When it warms then it starts to stall while idle, so I have to stop, park and start again.. It even happens when engine pulls the car forward.. Engine'* rpms become unstable and it starsts to jerk with the vehicle.. Worst thing is that it does not happen always.. During this the yellow "service engine" light goes on and off again (not blinking, it takes some time)..
For information.. Engine runs up to maximum rpms and has full power, it easily let the vehicle go above 160km/h..
Air filter is new, hoses and wires seems ok, coils have good resistivity, spark plugs' cables seems good, going to change spark plugs..
