I have a problem with my Corsa B X10XE 1998.
This happens quite often when driving in speeds above 90 kmph.
The engine management light lits up and the engine loses power. With
the light on I can barely maintain 80 kmph. At first it seemed that the light
eventually turn off itself at random, and the engine went back to normal, but I then
discovered that it happens when I release the gas pedal and then push it back
down. And if I slightly move the gas pedal up and down all the time I can avoid
the problem almost completely when driving on a flat road. As soon as I go uphill
it gets harder to avoid even with the gas pedal trick. Under 90 kmph it usually
happens when I accelerate hard. It almost never happens under 50 kmph.

This is the fault code read:

P0130 Not Present
(2) O2 Sensor Circuit Voltage Low

Searching around the internet, it seems like it could be the MAF sensor.
Any ideas?

i recently had this problem

i attempted EGR replacement, but in the end stuck with original,
Air flow meter replaced for NEW.

Whole thorttle body replaced, this included the ICU, i feel my old one was also shot.

its a hard one to pin point mate. hope you get it sorted it drove me nuts.

Have the same problem, but am replacing the Throttle body and ICU asap. Hopefully this sorts it but, Car hasn't been started for weeks so may take a while to turn over.

Check out my project log for a run down of my probelms with this issue.
I had removed and cleaned my old Throttle body, so i loved knowing it was spotless, butterfly valve etc. i think all it needed was a new ICU,
but the mechanic wouldnt hear anything i had to say about cars. in the end he reaplaced the whole throttle body with a 2nd hand one with ICU etc, who knows it probably came with a throttle position sensor etc. i havnt brought myself to remove it and check how dirty it is. but id love to clean that butterfly valve etc. I still need to lower my Revs also.

Maybe over xmas break from work.

i had this problem, i just needed a new air flow meter and it ran fine after that

Thanks for the replies.

It turned out the problem was a crack on the catalytic converter. Air leaked in and interfered with the lambda sensor. The car runs perfectly now.

Wow that's a new place to look.
