is it stalling when warm ? ie... when you slow down at lights ?

 

[garymitch]

no. it run's perfect. its just this starting when its warm.

ok has it had a service recently ? could be a dirty air filter? stick a new 1 in see how it is then

 

[garymitch]

yes it's been serviced about 300 miles ago.

could it be something to do with the starter motor?
my friends punto's power steering only messes up when warm turned out to be the motor so just speculating

 

[andy]

yes it's been serviced about 300 miles ago.

if its had a service including filter, iam thinking low compression,fuel injection fault or ignition fault

the compression is fine. was checked.

iv just been told it could be the auto choke senser on the head.

are the revs not dropping when the engine has warmed up ?

 

[Shaun]

would that stop it from turning over?

yes they are.

Ive looked it up on Autdata for you mate.....heres the results....
ENGINE HARD TO START WHEN HOT.....CHECK THE FOLLOWING

1..FUEL PUMP NON RETURN VALVE
2..FUEL PRESSURE/DELIVERY RATE
3..AIR INTAKE AND VACUUM CHECK FOR LEAKS
4..ENGINE COMPRESSION
5..(ECT) COOLANT TEMP SENSOR
6..INJECTORS
7..ENGINE MANAGMENT WIRING/CONNECTIONS
8..CATALITIC CONVERTER
9..ECU FAULT

This is the list autodata says to check.....hope it helps mate

sounds like the idle speed bleed screw is set too low

when cold the IAV autochoke opens and the engine revs up fine.
but when warm the IAV closes, lowering the revs to the base idle set by the idle bleed screw.
when you restart the warm engine with the IAV already closed, the base idle rev is not high enough to maintain momentum.

increase the base idle speed by unscrewing the allen key head behind the TB till it revs at 750rpm warm and 1200rpm cold.
