Ok , heres how my corsa is running. Rather than say its running like a bag of shit, heres basically how it goes.
Very lumpy idle 600 - 700 rpm.
Car is slow to pick up to around 3000 rpm , then all of a sudden its very quick 
Running rich.
Had it at the rolling road today and they have said the lambda sensor needs changed - there was a 0 voltage reading. Would that cause these problems ?
Also I have been using an x14xe ECU which Ive been advised to change , which all going well i should have one off Dave A
Quite pleased with how it runs when it goes but this is annoying me !!

think yourself lucky yours is a 1 wire lambda sensor
the fiat im working on needs a 4 wire and its about 3 times the price

Try a local (independant) motor mactor, i got a lambda sensor from the first one i tried round my way - although the problem in my case was HT leads so the lambda was un-used and returned

quite similar yes - a mate of mine (ex vaux mechanic) got a squirty bottle with some water in and just sprayed a light mist over the HT leads where they meet the engine (at the end) with the engine running - This showed the no.1 lead to be arcing

I was only having problems when it was wet, hence the leads were getting wet - plus it struggled to start at times.
Could be worth just trying that little test, cant do any harm but i would have thought rolling road ppl would pick up on that tbh

and as mentioned, dont buy 2nd hand, get new.
just because you buy 2 from a scrappy, doesnt mean 1 will work, let alone both...

if you have got the one wire lambda sensor i think they are the same as the 1.4 in which case they have them on ebay cheap.

Did a paperclip test - the lambda sensor I got works !
So the codes I got were :
44 Oxygen Sensor - AIR Mixture too lean (was running rich as fook beforehand)
24 Vehicle Speed Sensor
33 Map Sensor High Voltage
56 Air control solenoid - Low Voltage
Anyone know if these are whats causing poor running , and their reason ?
