Goneracin Posted August 20, 2017 Share Posted August 20, 2017 I have a 2014 Fusion SE 1.6L manual, just hit 70000 miles. The car drives fine, but occasionally on startup idles a bit rough and low. It eventually smooths out. I think I have felt a slight skip or sputter under full throttle, but it could be my mind playing tricks on me. The other day the CEL came on. Ran the codes and got cylinder 3 misfire. I reset the code, changed the plugs with Motorcraft OEM plugs, greased the coils and it seemed to run fine. The plug for cylinder 3 did seem to have just a bit more oil on the threads, and maybe a bit more black on the electrode. So I have reason to believe that it is not a false reading, that cylinder does seem to be a tad richer. The code came back again yesterday, still cylinder 3. I am going to swap coils between 3 and 4 and see if the problem moves. This is the first time I have run into this problem on any of my ecoboosts, so my question is, should I be looking at other causes that are more specific to ecoboosts or the 1.6? (I also plan to run injector cleaner on the next tank of fuel) Thanks for any advice or help you may have 0 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted August 22, 2017 Share Posted August 22, 2017 Don't know what a 1.6L specific issue might be, but generally on the GTDI engines, misfires usually end up being related to fuel injectors. Sometimes it is plugs, and forced induction engines do love to eat plugs for breakfast. Rarely the COPs. Valve cover leaks are known to happen from time to time, so if you find any pooling oil in the plug well, that is what it is. No harm in trying a fuel injector cleaner, but I only recommend something of the quality of Techron Concentrate Plus or BG 44K. What Techron can't get out, BG can (personal experience). Keep in mind though these fuel injectors run under very high pressure, so any deposits on them are also coated on under high pressure. The cleaners have been developed for much lower pressure situations like carbed engines and fuel injected engines of the PFI variety. That is why the final solution usually ends up being fuel injector replacement instead. 0 Quote Link to comment Share on other sites More sharing options...
Goneracin Posted August 28, 2017 Author Share Posted August 28, 2017 Thanks for the input. I did run Techron for the cleaner, and I am planning to put another bottle in when I fuel up today. This morning when I started the car it idled a bit rough. Then it got worse and stalled out. I got out of the car in my garage to get my scanner incase a light came on, and I could smell coolant pretty bad. No smoke, no puddles........ so maybe its seeping past the head gasket into the cylinders while the car sits? Ever heard of this happening around 70K miles? 0 Quote Link to comment Share on other sites More sharing options...
Thomas R Posted November 16, 2017 Share Posted November 16, 2017 I ran across a video an Youtube from a Ford technician. He said that he is seeing misfire on cylinders 2 & 3 on high mileage ecoboost engines. He has talked to the factory and they told him to look for carbon buildup on the intake valves. He checked and found carbon buildup on intake valves for cyl 2 & 3. He attributes this to the PCV systems sending oily vapors back to the air intake near cyls 2 & 3. There is a can that is supposed to collect the crankcase oil, but I haven't researched it yet. Running injector cleaner thru the fuel system won't hit the intake valves on direct injection engines. 0 Quote Link to comment Share on other sites More sharing options...
Goneracin Posted November 16, 2017 Author Share Posted November 16, 2017 Sorry for the long wait but the problem has been fixed. To make a long story short, my dealer found that there was a safety bulletin for all 1.6 Fusions and Escapes, concerning coolant loss and overheating and cracking cylinder heads. The car was pressure tested, found there to be a leak in cylinder #3. Ford decided to replace the engine with a brand new unit at no charge. I had them replace the clutch too while they were in there, so it cost me $150 for a new clutch. I would say it was a pretty stand up job of Ford to do this on a car with 72000 miles. Let me know if anyone has some questions, I will be happy to try and get you the info to get your car fixed too. 1 Quote Link to comment Share on other sites More sharing options...

You're talking about a catch-can. We've had this discussion previously. See this thread. 1 Quote Link to comment Share on other sites More sharing options...

I don't really get on here much, so I just saw this. No, the engine didn't shake at all. Honestly I couldn't even tell there was a problem except for the check engine light and the coolant smell in the garage when first started. It ran fine. 0 Quote Link to comment Share on other sites More sharing options...

Let me know if anyone has some questions, I will be happy to try and get you the info to get your car fixed too. Do you still have info regarding this? I’m having these same issues with cylinder 3. I’ve replaced spark plugs with all new OEM & swapped coils around. That fixed it for a few days apparently because CEL went off, but came back on 5 days later. I’ve put a new coil in at #3 & have driven it a few times, but light is still on. I’m going to try swapping new coil around to see if that has any effect, but it sounds like fuel injectors is the next on the list of things to check. However, if I can get the info you described above & take to my dealer, I can at least have them start there. Thanks. 0 Quote Link to comment Share on other sites More sharing options...
Goneracin Posted August 20, 2019 Author Share Posted August 20, 2019 Have you read the check engine code? When you move the coil, does the misfire move? 0 Quote Link to comment Share on other sites More sharing options...
Achester Posted August 20, 2019 Share Posted August 20, 2019 I swapped coils & spark plugs around & that would get the CEL to turn off for about a day & a half, but it continued to come back on. After trying that 2-3 different times & the cylinder 3 misfire continuing to be the only code that would come up, I ended up having to take my car to a repair shop (a reputable one, but not the dealership because I've not had good customer service experiences at my local one). They replaced a faulty fuel pressure sensor which, again, fixed it for a few days, but the CEL came back on showing a cylinder 3 misfire code, so back to the shop. After some apparently intense diagnostics (I say that because it took at least a week), they called me saying that there was a crack making a coolant leak occur around the gasket in the cylinder that needed to be fixed/replaced. After them having my car for over a month & me paying over $3,400 I finally got my car back & so far, so good... Despite the ridiculous amount of time it took to fix my car, I still fell that they treated me well customer-service-wise. They gave me a free loaner vehicle to use the entire time they had my car, saving me a bunch of money because I would otherwise have had to get a rental...something the Ford dealership would NOT have done. All that to say, it's fixed & hopefully no more issues for a looong time. 0 Quote Link to comment Share on other sites More sharing options...
MuzzyBowMac Posted November 15, 2019 Share Posted November 15, 2019 Hello, So I was just reading your post for obvious reasons. My 2016 ecoboost fusion 67K on it just started all the things you spoke about. You story sounds exactly like mine. Ford is aware of the issues on my car. NHTSA: 10163592. So how do I go about not getting soaked at the shop.? Any help would be greatly appreciated. 0 Quote Link to comment Share on other sites More sharing options...
Goneracin Posted June 5, 2020 Author Share Posted June 5, 2020 Sorry for the late response, I'm not on here much. Ford replaced my engine because it was a known issue on the 1.6. If you have a 2016 it is probably a 1.5, and I am not sure if it has the same issue. However, you need to go to a good dealer and have them look and look and look through all the recalls and TSB for your car to see if any are at all related. 0 Quote Link to comment Share on other sites More sharing options...
