VCCA Home Forums GENERAL DISCUSSION New User Forum New user with Chevy Matiz -> Engine shuts down unexpectedly :(

Hi guys,

Im new to this, and I hope I'm at the right place even though my Matiz (manufactured in 2005) M200 is a "modern" car compared to the ones which you guys seem to be talking about mostly here :)

Since a few days, the engine shuts down when pressing the acceleration pedal, so we gave the car to a garage. First they told it's probably either the steering pump or the air compressor. Now after they changed the steering pump which didnt fix the problem, they told it's surely the air compressor.

Do you guys know whether this could be valid? Could a bad bearing really block the belt to cause a engine which goes off? Im wondering why this seems to happen when pressing the acceleration pedal and not already in idle mode? I mean in idle, the car doesnt provide much torque, is it? So why can it still cope with the blocking bearing?

Is the steering pump and the air compressor on the same belt, which I just assume now!? In case yes -> is there a short belt available from some third party manufacturer to bypass the air compressor and only connect the crankshaft and steering pump? I could live without the AC here in germany... ;-)

Thank you very much in advance
ANY HELP IS MUCH APPRECIATED

If the air conditioning compressor is locked up the engine will not turn over with the starter let alone start.

That sounds also like a valid argument, thanks for the hint. So you'd say it's def. not the air condition compressor?
What else could it be?
-> Defect lambda probe? (but than there should be a faul code entry, which isnt according to the garage)
-> defect rpm-sensor?

So the car starts and runs at idle.? .If that is so..When you push the accelerator, it dies...On the old ones its called stall..which is usually the carburation..One more opinion to think about....Good luck
