    Today I tried starting my car and it wouldn't run. Instead, it made a whiny electrical noise. First time my Focus ST had ever not started in the 3 years I've owned it. Went to check the engine bay was greeted with this abomination: It looks like some critter, mouse, or freaking demon decided...

    I have a 2016 Focus ST. The car has an intercooler, intake, bags, and a cobb access port stratified tune loaded. (Note: Previous owner removed fender liners and Vents installed into the hood that are operational) I drove the car in the rain to work, went thru a large puddle very slowly and...

    I have been having an issue where my engine rpm at idle will drop down to 400-500rpm sounding like it is about to stall before it recovers back to normal idle rpm. The dealer is telling me it is due to coolant intrusion in cylinders 2 and 3 causing them to misfire. They also said the only fix...

    Was driving on the highway and got off the exit, while sitting at exit I hear something that sounded like pebbles/glass going through a fan or like plastic crinkling up, and then my A/C stop blowing cold air. When I got home I checked everything that I could since it is nighttime and didn’t...

    I drive a 2017 st2. Past 2 days when I hit 4th 5th and 6th the rpm’s will go up normally, then fall back down (usually around 1k) then slowly creep back up. This is my first stick car so I’m not sure if this is clutch or not. Car has 47500 miles on it. 1-3 feel completely normal and there’s no...

    Good evening! When I am shifting, my RPMs won’t drop and I am having to drive like a grandma so I can shift properly. I recently adjusted my shift cables after randomly finding a video explaining, “if 3 and 4 gear are difficult to shift, do this”. Now my gears shift like butter but I am having...

    I'm having an issue where when I'm stopped and idling my car vibrates and makes that shuddering noise that it makes when it stalls almost? It does that for about 2 seconds and returns back to normal idle. The needle also seems to drop to like 500 maybe 400 rpm when it does that. I'm also having...

    So I don’t quite know what the solution to this is so of someone could help me out that would be great. I’m like 90% sure I have oil spraying out that hole right there in the middle. Can’t get it in camera too well but you can see it kind of bubbling in there when the car is on and when you turn...

    Hello, I bought my 2015 Focus ST about a year ago at around 74,827 miles. The car came with a Cobb cold air intake and a chopped exhaust as far as i know. This led me at the time to believe that this was someones first "fun" car or first car which means it could have either been beat on or...

    So I have a tiny little oil leak presumably on the left side of my engine at the top. The leak seems to be right beside a belt and pulley. This is a 2014 ST with only 50k kms on it. It seems a little dark around that area and I'm wondering if this is an easy fix or if this is a tough one. Is...

    Hello, I’m relatively new here and would love some incite. I recently got my Ford Focus ST (ST3) and did some bolt ons and an exhaust and got it tuned (stratified). I got the car at 36,xxx. and have 41,xxx miles on it. Long story short I melted a hole through one of my piston heads and am...

    I am pulling the engine/trans from my 2017 FoST very soon (cylinder #4 ringland), and I have limited room in my garage. I haven't been able to find a clear answer- can I lower the car (engine pulled) onto the wheels without the cv axles and nut installed into the hub? I need to move the car out...

    Hi all! I recently had the piston rings on CYL 1 fail and am in need of a new engine. I've seen some threads on escape engines working as replacements but didn't know if fusions were compatible as well. I have a 2014 ST and have been looking for that year for a donor car.
