I'm searching to solve a few problems on a aero S1 2002 version (numer 142).
When we were driving the car, the power comes nearly to zero, and we let the car goes on the side of the road. The engine accelerate and decelerate without we press or depress the throttle pedal. We stop the engine, then we restart, and the engine doesn't rev at iddle, it stops when hot. Now, we can drive the car, but it seems to have lost some power. When the engine is cold, it revs at iddle, but when hot, it's always stop when the foot is not on the accelerator. And we ear like a suction noise for a second (like some air leak) when we put the feet on the throttle. Any idea where to look after ?
