2005 Megane cold start issue

[Ukjayy]

Hi, hope someone can help me with my car issue.
My 2005 Megane 1.6 petrol has a strange fault. When first started, the engine runs ok but if you press the throttle the engine seems to want to cut out. If you leave it for around 30 seconds you can rev it as normal.
The coils have apparently been replaced recently (by the old owner) but this issue continues.
I've read that it could be the coolant temp sensor, but hope you can point me in the right direction.

Any ideas regarding this fault would be really appreciated.

Thanks.

Try changing the coolant temp sensor, not expensive or difficult to do.

Thanks jonny, will give it a go. If that doesn't work what you you try next??

Cheers for the response.

Try cleaning out the air intake, in and around the throttle flap area. If
that doesn't cure it........A fault code readout can take all the guess work out of it and should point you in the right direction, saving you money in the long run.

Thanks again, I'll give it a go.
Cheers.

Hi, I've now replaced the coolant sensor, but the fault remains. Had a quick look at the inlet, but it seems ok.
I've been considering buying a fault code reader, but will this help if the engine management light is not on?
If you think it's still worth a go, have you any experience with a specific brand code reader?

Thanks
