the_white Posted February 27, 2010 Share Posted February 27, 2010 Hey there I have new MK7 fiesta with 1.25 82k petrol engine and 20k driven. Since 8k, have problem after starting cold engine. Normally, when I turn ignition on and start engine, I'm waiting 5 seconds, and then start with moving car (slowly depressing clutch, pressing accelerator),in this moment engine starts skipping(seems like dramatic loss of torque). Then it starts to accelerate strongly. Sometimes it is dangerous when somebody is parking close to me... This happens only when engine is cold and: - Temperature is higher than 0 Celsius (in colder weather and, it not appear) - only with Super 95 benzin (98 and higher fixes problem, but also more expensive :) ) do you have any idea what to check/repair? thanx Quote Link to comment Share on other sites More sharing options...

"The pipe others have refered to is the engine breather. it's often neglected at service. for a few quid you should fit a new one (looks like popeye's pipe) and also the replace the little orange membrane on the other side (inside the aircleaner".

the_white Posted February 27, 2010 Author Share Posted February 27, 2010 Thanks much for links ;) Maybe there is something wrong with that sensors. (it doesn't make sense that it happens only in temperatures over 0 C) Can you please send me any example of this engine breather? is there possibility to use it without damaging smthing?(fofi is under warranty) But even though, most strange thing is fact, that everything goes fine when I'm using Super 98 or 100 benzin. Maybe something with wrong ignition advance? Quote Link to comment Share on other sites More sharing options...
Valentino Posted June 18, 2010 Share Posted June 18, 2010 i have the same problem but i found the solution....dont start moving by releasing the clutch and pressing throttle but just by releasing the clutch easy...like with a diesel,the engine wont die,the car will move so move a few meters and than press the throttle...the car will move with 1200 rpm so it s no harm done...i asked at a dealership ford and they told me that this is a fault on most of the 1.25 engines...

blade Posted June 18, 2010 Share Posted June 18, 2010 it is not a common fault on 1.25,probably something to do with ECU,go to your ford dealership,if the car is under warranty they will do the software update for free.... Quote Link to comment Share on other sites More sharing options...
