Car Dies?

[SNaray8442]

Sometimes after a high speed/rev run my car will just die.

I'm not over-revving it. It just dies and I have to restart at high rate of speeds, not safe.

Any ideas? MAF? No codes.

Thanks!

Model, year and US/Canada or RoW please?

Have you checked for pending fault codes?

1999 C2 US

Codes P1124, P1126

[Loren]

P1124 Oxygen Sensing Adaptation Area 1 (Cylinders 1 - 3) - Rich Threshold

P1126 Oxygen Sensing Adaptation Area 1 (Cylinders 4 1 6) - Rich Threshold

These mean your car is running too lean and the DME can not make the mixture rich enough.

Potential causes:

- Intake air system leaking or exhaust leak (air leaks ahead of the oxygen sensors is a common cause of these faults).

- Fuel pressure too low.

- Volume supply of fuel pump too low.

- Fuel injectors fouled.

It is also possible that your MAF is giving errant readings. So, it would not hurt to clean your MAF or have the air flow tested.

I've got a whole nother thread about the codes. I've done a lot of troubleshooting and haven't found anything.
