Latest CDTi Issue

[kryton01]

Just picked my Veccy CDTi 150 up from the steelers after they advised me not to have two injectors replaced after they could not guarantee this would cure my problem. Their Tech-2 had apparantly detected injectors 1 & 4 not working properly but this took them 3 hours to diagnose.
When I collected car, it had been stood for three days but started perfectly with very little smoke which cleared within a few seconds. Drove the car back without problem (although it does feel a little hesitant still).
I seriousy think that the injector loom needs replacing and not the injectors but wary of spendng £127.
What do you think?

my car was a little like that so i asked the dealer's and they said all was ok after an ecu update....and low and behold it was much much better......

I read somewhere that if you disconnected the battery for 15mins it would reset the ECU. Is this right and worth a try?
