You don't say if this is fuel injection or carb?

On a Carb model it could well be an air leak weakening the mixture.
Effect would be masked by the auto choke when cold.
Look at the butterfly bearings and maybe the gasket on the inlet manifold.
If it is an injection model download the fault codes and take it from there.

Hi,

In addition, it could be a trick with the auto choke. On 405s, there was a
manual choke retrofit available at Peugeot.
If it was a fuel pump problem, the car wouldn't run at all, or start for a
couple of seconds, not more.

It is pretty unlikely to happen, but you could spend an hour checking the
valves clearance. Pretty unlikely 'cause there are rods, and not the
"classic" bolt & screw clearance trimming, this is very unlikely to move.
The main inconvenient is, that's a real pain to trim (you'll need to
calculate the right rod thickness, remove the camshaft, and so the cambelt,
put the camshaft back on, fit back another timing belt & tensionner)...


Tomorrow I'm gonna move to vacation. I wish you a happy motoring.

HTH,

 

Sorry Bob its got a carb.i think the float level might be out .

 

In the old days that would indicate a leaking copper float. Aren't the
modern ones solid construction though?
