Hyundai Repair: Hyundai Atoz, air intake hose, air flow sensor


Question
I have a 1999 Atoz and for the past two months I have been having a problem where you can be going along the road and suddenly there will be no power, the car idles but when using accelerator does nothing, no lights come on and after a few minutes. The car is running ok otherwise but its getting more often, two garages have looked at this and cannot find anything wrong.I have had a new dist, coil plugs etc .

Answer
While I don't have any specific experience with the Atoz, I can give you a few items that can cause your symptoms:
1.  low fuel pressure
2.  broken catalyst, intermittently clogging catalytic converter
3.  air intake hose leaking or loose
4.  air flow sensor reading improperly.

It's quite possible that the shop may need the problem to be occurring while they're running the tests in order to determine where the problem lies.
