In 2013, a third-generation Ford Focus 2.0MT was produced. The crankcase vacuum hose broke once, and after repairing it, the instantaneous fuel consumption display had a problem. It originally showed 0.7, but now it shows 0.9-1.0.

It consumes fuel alot
I’m tired about it, I have changed the plugs and wast the fuel system and plugs head

Hey everybody, a few days ago, I put a cold air intake on the 2014 Ford Focus SE from K&N, I started off good, but then suddenly it started drastically dropping my MPG to the floor, next day I thought I‘d just clean the MAF sensor with the MAF sensor cleaner, and I did, after that the car drove pretty good, but then I fuelled it up with fuel I usually put in (89), and when I start up the car I see a check Engine light, so I take out the OBD 2 reader and it shows me hella transmission faults such as : P0805, P0809, P2872, P286F, and a few other problems, after that it started going up to 3000 rpms on the first gear, and have horrible shifts that shake up the whole car, does anyone know what to do?
