Hello St owners, The other day I was sitting in my car waiting for an appointment and I was noticing a slight bogging feeling. After I felt this I closely watched my Afr and I had noticed every 10 seconds it would dip down to 15.88 then spike up to 13.23. Then would return to 14.7 for another...

I know there are lots of threads about this but I just wanted to get some answers for my car's situation on fuel choices. So I have a 2013 Bone Stock focus ST with 118k miles/180k km on all original trans, motor, turbo, etc. I currently use 89 but is it worth going for 91 at the pump. I heard...

Have codes P1450 (Unable to vent tank vacuum) P2196(O2 bank 1 stuck rich) , and P0301 Cyl 1 misfire. P1450 and P2196 fall under Recall TSB 15-0034. Car ran out of gas a week ago at 10 miles to empty, so definitely think this falls under it. Going to take it to Ford soon. My question is does...

So I’m lost at what else could be the issue looking for some idea. 2017 with 82,000 miles threw a p0302 a few weeks ago. You can clearly hear the misfire and it stumbles quite a bit around 2,000 rpm.Checked coil packs, replaced and properly gapped spark plugs, checked and cleaned all fuel...

Hello, I have a Ford Focus St 2016, with a air intake from mishimoto, Cobb accessport and straight pipe. Yesterday I noticed that my air fuel ratio was really high when I was out throttle, it was going up to 43 -50 but when I was in idle and full throttle it was 14.7... Is this bad I have...

I have a 2016 Focus ST and I have the Cobb AP set up showing my actual AFR, on idle it’s reading normal between 14.2-14.7 but once I start moving, different gears and rpms haven’t seemed to show any difference, it will consistently run 14.2-14.7, on occasion it will drop to 12.5 but from what I...

So i’ve been thinking about upgrading my fuel system for a long time due to the fact that besides the turbo it is the limiting factor on these cars. I do not want to do the typical 2 or 4 port aux fuel way due to the difficulty of install and things that could potentially go wrong if something...
