peugeot 406 glx 2 litre petrol w reg - s1442
I wonder if anyone may be able to help.I have an ongoing problem where ,only intermittently, my exhaust makes coughing/spluttering noises.It was recently replaced and these noises then started.My mechanic replaced the exhaust again,but it still carries on making these noises,usually if i am coasting down hill or have the clutch down.
More importantly,but again intermittantly,when slowing down the car will stall as i have the clutch down to change to a lower gear.This is a bit dangerous as i loose the power steering in an instant.
My mechanic has checked the coils,cleaned the carbon off the butterfly and replaced the idle valve,but all to no avail.

Can anyone help ?

Could be many things, but not likely to be the exhaust. Try checking the ignition timing, timing advance,idle speed. Also check that the engine is not running rich. ( and the choke, cold start is not staying on )
