First of im new to the forums. Ok ive had my Fiesta ST for about 10 months now, and it has about 6000 km on it, so its still new lol, the problem is that every time in the morning, (specially now in winter), i have to warm up my baby for about 10-12 minutes, if not, i just cant move it, the first time i turn it on it usually just dies in 3 or so seconds, next time i pump it 3 times before turning it on and it usually stays on after that, but if i rev it up just a little, the engine starts to die. I took it to the dealership and they told me that its an "error in the valves", and that apareantly some other fiestas around the country have the same problem, (i live in Mexico btw), my question is, have any of you had this problem? if so did you fixed it? how?

Hi & Welcome
Can you tell me:
What fuel grade you run your ST on and
What fuel grades are available in Mexico
It sounds like you're running on 91 RON
You shouldn't press the throttle at all while starting whether warm or cold, the ECU does that for you.

Goodness! Quite bad. The standard fuel here in the UK is 95 with most places stocking "premium" stuff at 97 or 99 octane. I know a few Greek members had problems with the way their cars ran because they had fairly low octane fuel too.

I found sometimes the only way to start mine is to press the throttle...normally after a short journey

Arr sorry I'd misread it for meaning that 95 was the highest available. In that case then running on 92RON isn't good. The only other possibility I can think of is are there any additives available which could uprate it, in the same way as ones were available to allow unleaded petrol to be used in older cars after you could no longer buy Four Star? I'm not sure if this is possible though. 
You can buy octane boosters from most car accessory shops and even petrol stations
JUST MAKE SURE ITS NOT ONE THAT CONTAINS LEAD OR A LEAD SUBSTITUTE, you'll kill the cat if you put lead in.
Your car should be mapped to run on 91 unless it's a Euro spec that was imported

OK it's an import but was it bought from a proper Ford dealer with warranty?
You may be able to get Ford to change the ECU for one that's mapped to your 91RON petrol. Or at least the Euro III set up instead of the Euro IV that yours is trying to run to, it will run better with the Octane booster then.
If not then you may have to get the car re-mapped yourself.
Surely people like DreamScience and Bluefin would be able to cater for this??
Also, I'm not tying to teach you to suck eggs but there must be a petrol station somewhere that sells the higher octane fuel.
Why don't you do some research on the web to see what other stations are offereing?
Even if you have to go a bit out of your way??

Mmm I've just done a bit of research and it looks like you can only get "Magna" which is 88RON  and "Prenium" which is still only 92 RON I think you need to look at buying something like a Bluefin and getting them to do a Map for the 92RON fuel. If it's a genuine Ford import though you should make them sort it for you as Europe spec Fiesta STs are mapped to run on 95 RON Unleaded ONLY. The standard model Fiestas have a bit of adaptability in their programmes and can sense when the fuel is a bit crap and back everything off to try and adapt but ST will not, it will only run on 95RON. The comment the dealer made about it being the valves suggest you may also need to use an addative that contains an upper cylinder lubricant. BUT MAKE SURE IT IS NOT A LEAD SUBSTITUTE. I'm sure people like Slick 50 do an Upper Cylinder treatment, try at your motor store or see if you can order stuff online? Also you need to make sure you change the fuel filter very regularily from what I have been reading. Good luck mate, I hope you get it sorted

It would be an exchange ECU so they would have to order it and have it shipped over. Then about 2 hours fitted. Tell them they need to contact the European technical support to find out what can be done to run the car on your Fuel. A bit of advice, Why not join the South African Fiesta ST Forum, those guys on there are really helpful and I know they have some crappy Fuel as well but their cars are not Euro imports they are built especially for SA. Site: http://www.fordstownerssa.co.za/ST Forums: http://www.fordstownerssa.co.za/forums/You may want to tell the dealer that this may also be a Throttle body fault if the car is allready mapped to run on 91. It looks like the SA guys are suffering with their Throttle bodies.
