New car, fault no.3. Ignition. Sort of.

OK, here's a strange one.

First thing, when the cars cold, the ignition starts and idles perfectly and off I go. When I've stopped and the engines still warm, when I hit the start button, the car starts, rev counter fires up to about 1500rpm, then it drops down, but instead of idling at around 900rpm, the needle drops to about 4-500 rpm then stalls.

The only way to combat and keep the engine running is to keep the revs up with the accelerator. By the time I've come to the first junction, the engine's happily idling away at 900rpm.

It's not a massive problem, but it's irritating nonetheless.

Any ideas? It's back in the garage on Thursday for them to check out the bootlight/parcel shelf problem and I'll get them to check this out while they're at it.

i would hope the idle just needs adjusting however it may be the automatic choke failing just get em to fix it

I thought about the choke, but why only when it's warm? When it's been stood overnight it starts fine. Maybe it's me...

if the choke is still open when the car is warm and doesn't need it, it will 'suffocate' the engine and probably stall. not sure though sounds weird let us know how they fix it and what it was.

There is no choke on modern cars! The ECU changes fueling and airmix constantly to suit the conditions.

I had similar problems - once apparently down to a faulty TDC sensor and the other time attributed to a faulty coolant temperature sensor - see video here:
