Corsa 1.0 - lack of power

Thanks for the Cam Position Sensor info.....more potential problem areas!

I got a price for the Lambda sensor..Its £106.67 + Vat from Vauxhall...somenbody posted a message saying its about £15. Who can supply me one please?

This car is running very badly. If the car is under load and you put your foot down it holds-back very badly. If you take your foot of the gas a little bit it goes better. I wondered if this could point to the exhaust/O2 mixture in the Cat becoming rich and the Lambda sensor not being able to signal to the ECU the correction required.

Can anyone comment on this idea please?
Thanks.....john

I found this explanation (people may find it helpful)....Lambda describes an equivalence value in percentage of the chemically correct air-to-fuel ratio for any type of fuel. If the air fuel ratio measured in the exhaust pipe of an engine is at the chemically correct (stoichiometric) ratio of air-to-fuel, lambda is equal to 1.0. In the case of gasoline, lambda 1.0 is equivalent to 14.7:1 air-to-fuel. Lambdas less than 1.0 indicate the engine is running richer than stoichiometric, while lambdas greater than 1.0 indicate a lean mixture. If we measure a lambda value of 1.06 and we want a lambda value of .95, we simply increase the fuel delivered to the engine (pulsewidth) by 11 percent. This will place us exactly at .95 lambda. By using the Lambda Was or the Quick Lambda functions a tuner can quickly shape the fuel table to match the engine's exact requirements.

That seems steep even for vauxhall.
Try ringing around your local motor factors.

Unless it's some weird "only fits a corsa" probe you should get a pattern one

try giving this lot a ring dixons vauxhall spares
 
I was advised to change the MAF sensor instead of the Lambda. Got one for £45 from a scrapy and it solved the problem.

Here is another forum discussing this same problem.....i found this by doing a Google search on "corsa engine X10XE or X12XE"

Lambda Sensor and the MAF can be got from these suppliers....the Lambda can be found at £17 and the MAF at £47.

I previously had to replace the Crank Sensor and the Idle Air Control Valve, other people report the Cam Shaft Sensor can fail. Our car is still not 100% so i guess their could be something else lurking in the background.

Thanks to all who contributed........john

I know this thread is ancient.. but I'm trying to buy a maf sensor for my daughters corsa which keeps cutting out when warm (clutching at straws really). It's an 02 1L. how do I tell which part I need or identify the engine please?

there should be a part number on it if its a bosch unit, there are quite a few sellers on ebay now selling genuine bosch units. I bought one a few weeks ago, dont fit anything other than bosch or vauxhall sourced electrical parts for these as they are no good
