Hi All.

I have a bit of a problem with the engine cutting out when its warming up

it starts fine ,runs fine,until it it gets close to normal operating temp then

it cuts out ,if I leave it for 1 or 2 mins it will start up fine and run well till

the next time it gets cold then we start all over again.

I have run conzult and it gave 2 faults , temp sens and maf so I cleaned the connectors and removed the apexi filter in case water in the maf could be causing the problem and refitted the oem airbox and filters.

Now I am getting no fault codes and acording to conzult they are both

working fine.

But on the way to and from work today it did the same again.

Ran conzult tonight alls fine no codes but the problem remains.

Anyone got any ideas where to look next ?

sounds like PTU on its way out once gets hot ptu goes tits up and sends a weak spark,wiggle the connections to the ptu or even clean them with some electrical cleaner and reconnect,whats your base idle set at approx

Hi greg

The base idle is about 750 when hot ,the strange thing is the car runs fine when hot

but cuts out only when warming up.

Anyone ?

750 is fine,still think its your ptu,why not meet someone and swap a good working ptu over see if that cures it

thanks for that greg I think I,ll just buy a temp sens ,ptu and a maf and change them one at a time till its sorted .I spose i,ll need whats left at some point.
