Hi Brett and thanks for choosing JustAnswer.
My name is Vlad.
There are several reasons that could cause the situation you described.
You said you checked spark plugs, but I would start from replacing spark plugs with genuine Ford plugs. I bought my BA falcon XR6 ute with 128000 on the clock it it had pretty worn spark plugs, so I just changed it. You can get it cheap of Ebay.com.au or quicksales.com.au
It is also possible that you have a faulty ignition coil that starts playing when it is hot.If it is a coil, It will be hard to diagnose without a scan tool and they are pretty expensive unless you get it from wreckers.
Also, check your throttle body and thoroughly clean it with carb cleaner and tooth brush and rags.
I have heard that these BA falcons have had some troubles with idling and Ford released new software to fox this issue. Maybe it is worth to see you dealer just to check for available updates. I had my another BA XTsedan updated and it improved transmission shifting algorithm.
Thanks,
Vlad

Hi VLADGMRU , Thanks for keeping contact , i have ordered a set of new VDO coils from ebay and are about to head into town to grab some new sparkplugs , i remember when i had the plugs out they had a huge gap so hopefully by replacing the coils and plugs it will fix the issue . I will ley you know how i get on , thanks Brett

Hi Brett,
Please do not hurry to replace coils.
Change the spark plugs at first and see how it goes.
If it runs OK, then do not replace the ignition coils because genuine coils could be more reliable then aftermarket even though it is VDO.
Please let me know how it turns out.
Regards,
Vlad

Hi Vlad


The new coils turned up today and i grabbed the new plugs as well . Put the lot in and went for a good drive and all seems fine now . I put in the Ford 32Z plugs gapped at 1.3mm , got 6 new VDO coils off ebay for $145 . Thanks for your help , i was thinking a coil as it only played up when hot , fingers crossed its all good now . I can give it a quick rev when hot now and the motor comes back to an idle , doesn't cut out so all looks good , thanks for your input , cheers Brett

Hi Brett,
I am happy to hear your Falcon is ruuning good now.
Have a nice day.
Cheers,
Vlad
