Replaced the lambda sensor on son's 306 XSi this afternoon as Pug dealer said it was showing a fault code. Wiring was exactly the same colours so no problem there and it came out fairly easily ! Problem is that the engine management light is still on and it idles roughly still. Obvious question -- does he now need to take it back and have the fault cleared from the ECU or is there any other way to reset it?
TIA

Many thanks, I'll give it a try. Read the page and it looks like I should really clear all the faults/codes and see what happens!

Seems all is sorted now. He disconnected the battery for 10 minutes and it's running very sweet now!
Thanks the help and advice.
cheers, Len
