common problems with 1.2 16v (not the usuals)

[ditz]

anything common on these causing a hesitation from low revs?
checked all the loom all seems ok, has had a new map sensor on it recently
came up with the following fault codes -

fuel circuit
pre cat lambda sensor signal

put it on the gas anyliser its running lean (co-0 hc-1 lambda 1.03)
lambda likely to cause this?
funny thing is i cleared the codes and it seems ok-- not going to look untill tomorow but any ideas appreciated

cheers

Sounds like a faulty injector maybe or spark plug or check the bracket on the ECU at the back of the engine bay.

I get that sometimes as well, like a delay and slight stutter when pulling off. Its not always but occasionally with mine.

the brackets off at the moment all wiring is ok.
i have heard of injector problems although it does seem to run fairly sweetly
cheers for your help

thats the kiddy, its quite offensive on this one though.. only thing leading me to think its lambda fault is it seems to be switching really slowly on the scope

It almost sounds as though its fireing on 3 cylinders, which leads me the the injector excuse.
