Name: David. Ford Model: Mk8 Fiesta Zetec 1.1l ti-vct five-speed. Ford Year: 2018. UK/Ireland Location: Northamptonshire. Posted November 19, 2020. I have a question. I have always driven cars to around 3000/3500rpm before changing gear. I see in some videos people going up to 6000 as in video of my model of car below. #1 · Apr 11, 2015 Hi, I'm looking to buy a 2012-2015 Ford Focus with the DURATEC Ti-VCT engine. Any known problems/issues with this vehicle. I've had my 2002 Ford Focus for 13 years and it has been a great car except for the dropped valve seat. I learned a lot more about the 2.0 Split Port engine then I really wanted to but I'm an expert now! This post was written after I saw my engine stutter problem disappear after replacing a bad PCV hose. The engine stutter problem returned. Replacing the PCV hose did not fix my engine stutter problem. Additional info at post#3. 2004 2.3L ATX with 141K miles. I do not have a question, but wanted to share a fix and lessons learned. 2.
