THIS is what I like about you! As I've mentioned a few times here, I'm a Retired Ford Tech and Driveability Specialist. Back in the 80's, we had to DIAGNOSE Problems! Pinout Checks, Breakout Boxes, and often lots of disassembly and inspection - before we actually got to the root cause. (MUCH harder on EEC III and IV Vehicles!!!)😖 From what I've seen of Techs today - most of them operate by pure Procedure... Scan, work through the Manual (maybe), even something as archaic as pulling Coil Pack Plugs - to try to find misfires! If they do find anything - "Could not replicate customer concern" on the Ticket - and off to the Writer!!! 😠 I've seen it from Friend's experiences. WE WEREN'T ALLOWED to do that! You actually WORK the problem, like we used to do. I really appreciate that integrity still exists! Carmine ✈🚂🚙

I will always admit, early GM OBD Systems were MUCH easier to work with. And you're right, we'll leave Chrysler out of this - especially "Lean Burn".

I'm in the motor City and we don't do emissions here so she's now a 400hp unleashed beast. Off loading all that crap I have the car down to 3350lbs and ultimate sleeper status. 408 stroker with a 150 shot next. Upgraded rear, trailing arms, 2002 brakes and spindles. It was fun to build and only happens because the eec 2 and variable Venturi carb had to go. At 42k miles it was rough running to say the least.

Great video showing classic logical diagnostic sequencing of an issue especially when there are no codes set. It is amazing how the best mechanics that produce videos on RU-vid all have very similar steps they follow that, one by one, eliminates potential causes of the issue until there is only one left. Funny how this consistency in diagnostic techniques is so similar. I don't think it is a coincidence! All new mechanics should watch you, Eric O. and scanner Danner at the very least to lay a good foundation of being a vehicle diagnostician rather than a parts changer with a powerful parts cannon.

Hey, I have watched all of your videos and I can't remember any where you talked about a "carbon issue". You kept saying "carbon issue" and I kept thinking "what is he talking about?" It took until the very end of the video for me to realize that you meant carbon buildup on the intake valves. And, you seemed very confident, but the problem was on 2 and 4 but you said the PCV enters at 2 and 3. So, really looking forward to the next video to understand what the real problem was. The diagnostics were great. But I didn't see a real solution at the end. Love your channel, keep it going.

My 2013 Escape with the 2.0 liter Ecoboost engine was missing badly from 2000 to 4000 rpm. No error codes. The engine has been dealer serviced every 5000 miles and now has 120,000 miles. I put in new Iridium plugs at 100,000 miles. Lately, I have been driving short trips only and the engine sputters when accelerating. I decided to replace the spark coils. The engine runs 90% better. I used Motorcraft coils, because I hear that some other brands may cause radio interference. They are easy to replace in an hour. The cost of about $220 seems worth it, and Rock Auto got them to me in 3 days. I'm still getting some burble noise from the exhaust system near the cats or turbo. My mileage has improved too. So it seems true that the "coil on plug" coils do get weak after 100,000 miles.

Plug gap is a big factor when it comes to the ST and RS. 0.026-0.028 is usually the best gap to run since the gap expands over time. Purge Valve also is another culprit to look at replacing since these are known to seize up over time.

Great vid. I have a 2015 also. You did a video about six years ago on catch cans for ecoboost motors. I run radiums on both sides. My valves are like new. Im sure that if you look at the valves they have all kinds of build up. Walnut blasting will fix it. Most people that have performance di cars do it. VW, BMW, etc. all the same problem. Misfire due to carbon build up. All that carbon doesnt allow the right amount of air flow for proper combustion and the ecus are very sensitive. Great vid as always!!!

Today they take these small displacement engines and run them very high RPM and I just can't see them lasting 200k or 300k miles.

With original equipment? Likely no. The Turbo's are only rated for about 150K miles, and MANY don't make it to 100K...ask me how I know...yea..$3K total repair bill, turbo's weren't bad (price wise, about $700 each which isn't bad considering Ford used to pay $3500 EACH for them a few years ago), but the manifold is shot on one bank and has to be replaced as well.

You should test drive a ecoboost sometime. They don't have to Rev high. They all make their max output power before 3,000 RPM's! We have a 1.6 ecoboost in the fire escape. Full torque at just over 2000 rpm. It rarely revs to 6k. And I have 3 5 V6 ecoboost in my F-150. At 70MPH it stays in overdrive on the big mountain grades at just 2,000 rpm. You can't do that with a non turbo V8. Not in a Chevy, dodge etc. My ecoboost in the truck shifts well before 6000 rpm. It pulls hard at just 3000.

@steveneldridge6787 3 года назад

When the 1.6s came out I experienced this at the dealership. Had a car with a misfire on start but could never get it to misfire after warm. After looking at Freeze frame data it only did it on initial startup. I finally talked the customer into leaving it. I pressure tested the cooling system with the engine cold, pulled the plug and scoped the cylinder. Sure enough a head gasket leak could be observed as a tiny droplet formed and started running down the cylinder wall coming from in between the head and deck.

Thanks for a view into diagnostic tools you use. It's impressive what you can learn by using the engine sensors. That's quite interesting about carbon on the intake valves. I'd enjoy seeing you making the repair.

Every time you do an Escape video or EB 2.0 video I feel like I’m driving a ticking time bomb. 121k miles on my EB 2.0 AWD Escape. So far purge valve and AC clutch have been the extend of repairs needed. I’m hoping to get 200k out of it.

@johnp.5134 3 года назад

I'm actually relieved you have that many miles on yours. I have a '15 Fusion 2.0 AWD and I plan on keeping it as long as I can and I keep reading about coolant in the cylinders but I guess that's mainly the 1.5 EB. I'm currently at 45k miles.

@JustinLaNoue 3 года назад

Carbon cleaning is really the worst case and that's not at all the end of the world. The 2.0s are pretty good engines I wouldn't worry.

@@johnp.5134 We had our 2.0 ecoboost replaced on our 2017 fusion due to coolant intrusion. It was at about 30k mi, covered under warranty. Just keep an eye on coolant level. I happened to notice ours was often low and just happened to run across the TSB on this.

Hey so I installed a new ford engine into my 2018 Mustang ecoboost, and I think I’m getting ghost misfires 👻. I’ve checked coil packs, spark plugs ect. Only happening on cyl 2/3 . The codes I get are p0316,p0300,p0302 and p0303. Seems to be only on start up. I’m praying once I get this procedure done, it will fix my issue 🙏. Thanks for this video, as it’s definitely helpful 👍

@Ryan96se 11 месяцев назад

I'll be watching this as well. I have 91K on mine. Mine starts good when it's cold and rich. Most of the misfires start right after the initial rich idle starts to lean out and the idle just starts to waver on coming down. Kinda bounces a little before the final drop off and true idle. Then maybe a few misfires after a warm idle is reached but then cleans up after operating temp is reached. Just like this engine is doing but not quite this bad of a miss...yet.

@gmtech2012 Год назад

I'm a GM dealer tech and I see several misfire cases every week. Mostly it's cold start carbon issues and I'm still trying to come up with a way to prove that it's the carbon. I'm still running intake manifold pressure tests and seeing if a carbon issue actually changes the flow in the manifold compared to other cylinders, or cylinders that aren't misfiring.

@JP-uk9uc 3 месяца назад

Ethanol is just a fancy word for alcohol, it leans out the mixture and therefore causes a misfire when cold in my ST. I've confirmed it several times. The engine needs to be warm before it goes away. The only time I'll put ethanol in the tank is when I'm on the highway all the time. To solve the issue I fill up with ethanol free fuel at a co-op.

@deanmarsh1452 3 года назад

Changing oil frequently helps too. Less junk in the pcv to bake on the valves.

@ak2112 3 года назад

Had a 2015 ST bought back by ford (after 19k miles) for misfire CELs on cold starts. Issue started at 6k and ford just chucked parts at it. Injectors, plugs and even a HEAD. None of it fixed it and they bought it back for full value (after a lot of fighting). Got a 2016 replacement ST and it had the CEL misfire at cold start pop on at 15k. THIS TIME, Ford was smart (different dealer +a new recall) and determined it was the PURGE VALVE causing the issue. New purge valve installed and the car has been mint ever since (currently at 40k). You'll know it's the purge valve if the car surges at parking lot speeds in 1st gear on cold starts.

We switched to 2018 Ford Escape SEs for our 5 regional managers back in '18, with the 1.5L EcoBoost. All serviced by the nearby Ford dealer. One of the them has had issues with loss of power and rough shifting for about 18 months but dealer always said couldn't find anything. Earlier this month, when it lost power again while driving, dealer diagnosed a bad transmission with an estimate of $7700 to replace. At 89k miles!!! We're done with Fords at this point. It's utterly ridiculous that a modern vehicle transmission would go out at 89k.

@billkrause4585 3 года назад

Tip/s: What if you applied a can of Intake Valve Cleaner, maybe that will help those carboned up valves to seat better. I did that to my Ford Ranger XLT 4.0L and the guy who did the emissions tests at the Ford Dealership say the results were really good for a truck with 174, 000 miles on it. I too use Seafoam to a full tank of gas at times for the injectors, and use 5 ounces of Seafoam in the oil crankcase 50 miles before a oil and filter change and add it to a fresh oil change too. It helps things like the push rods, rod guides, and rocker arm lubrication & etc. It frees things up. Well, the engine is quiet and purrs at 174,000 miles anyway because of it. Also install a new radiator cap to assure not to overpressure the cooling system. If you shut off the engine and get gas bubbles in the antifreeze reservoir, you probable have a head gasket leaking. If you can't find a vacuum leak, replace the inexpensive EGR & PCV Valve to eliminate those. I had my truck for 19 years, I know a little bit that helps it run. Take your vehicle out the road and blow the carbon out of it the old timers would say. I take my truck out the highway and hit the passing gear a few times, ... you know, hit the gas pedal to the floor and let it down shift (passing gear).

@davea2288 3 года назад

From my understanding of the EcoBooost engines, there is a small amount of exhaust push-back into the intake runner because of the way the engine's valves are timed to make large amounts of horsepower. Because of that, and because of cylinder gas direct injection, there is no injector to provide gas spray cleaning on the backside of the valve. So, hot gases deposit themselves on the backside of the intake valves and the intake head chambers and condense and build up as carbon deposits. That makes the engine oil changes crucial to the life and proper running of these engines. BMW engines have the same problem and BMW has a method that uses walnut shells to remove carbon build-up on the intake cylinder ports and valves. in a sand-blaster-like manner. It is also my understanding that Ford engineers have yet come up with a Ford-approved method to deal with this.

Thank you so much for this thorough guide to troubleshooting misfire. I have a 2.0EB which is throwing cylinder 3 misfire that I'm trying to track down. I've downloaded Forscan and purchased ELM adapter but my Forscan program looks quite a bit different than yours. And I don't see anywhere to monitor cylinders like you've shown in this version of the app. Anyone else experience the same? Do you have to purchase extended license of Forscan to get access to cylinder monitoring?

@marathonfreak67 3 года назад

Solid video. Great diagnostics and explanation. As you went through the initial software checks my mind was running parallel. Basically check fuel, spark and compression. When did carbon buildup-based misfires even become a thing techs had to think about. This is silly in modern engines. The diagnostic software isn't FORScan, right? The video has a link to FORScan (good software for basic stuff) The video seems clear that this is not FORScan but the description links to it.

@JSW42 3 года назад

Most often carbon affects all the valves. It causes a hesitation, when cold, but rarely a single cylinder misfire. A partially plugged injector would be my first thought. It would affect the engine when cold but less when hot.

Doing a engine in one of these at the moment, Cylinder 1 about 50psi compression. Rings are shot, have done a few 2L ecoboost for low compression. If it's not low comp in these ecoboost 4 cylinders it's coolant leaks........
