Faulty Lambda sensor (?) in PUG 306 - thalamus89
Would a faulty Lambda sensor cause the following problem on my 1997 Peugeot 306 2.0 XSi?

On warm up it stalls until the engine is at normal operating temp. Also driving on the motorway the engine management light will come on for ages when going 60MPH+ Below 60MPH the engine light does go off.
I have checked MAP sensor, put in new stepper motor and engine coolant sensor.

Before I take to get the code read is it worth changing the lambda/oxgen sensor or could it be somthing else?

Sounds like the most common error for them symptons. Before buying a replacement just take it out and clean it up with a bit of meths / petrol to remove the carbon. See if it improves at all.
