06 Ford Escape Misfire With An Interesting Backstory

You know it’s going to be good when the client comes in with papers describing everything that has taken place! This client was extremely nice and gave us lots of info in regards to the misfire his escape had. He has done his own work and finally decided it was time to give up and bring it to us. So we take the info given and use it to help us but at the same time not distract us or make us go down a rabbit hole. Keep it simple. Find the misfire. We hope this helps! Enjoy!

Finally!! Someone doing secondary ignition analysis!! The ats scope is outstanding in that area!! This is how a pro does it!!! A++++

[@SouthMainAuto]

Good video Sherwood and you are absolutely right about using this method here and the pitfalls of swaptronics. I mean no disrespect by this but you asked for our opinions so I will give you mine on using fuel trims to diagnose what type (fuel or spark) for a misfire. I do not believe you can use fuel trims to determine the "type" of misfire. UNLESS the vehicle uses the rear O2 in its fuel control strategy. Example, when you are looking at fuel trims LT & ST and you induce an ignition misfire you will see the fuel trims elevate +10 to 15% ish. You typically will see the same thing with an lack of fuel induced misfire. I feel this is because the upstream O2 or AFR only can "sense" the O2 coming past it. A misfire regardless of the cause (lack of spark or lack of fuel) just turns the cylinder into a big air pump. However a lack of spark misfire does send raw fuel down past the upstream sensor it doesn't really "see" it so you usually don't see any big difference in the FT's with a lack of spark vs a lack of fuel. HOWEVER if the fuel control strategy of the car does use the rear O2 to make FT corrections then you will but not all cars use the rear O2 for fuel control. Now what I like to do is look at the the front O2's or AFR's AND the rear O2's during the misfire even and that will typically show you immediately what type of misfire you are dealing with. If the CAT is working and has lit off and you induce a no spark misfire you will see a rapid rise as the raw fuel gets burnt in the cat and on the contrary if you induce a lack of fuel misfire you will see the rear O2 drop off lean. In both of those case you will see a rise in the the ST LT FT's but the rear O2's will tell you the real story 😉 I hope that is all understandable and the short of it is, it may be more valuable when dealing with intermittent misfires to look at the rear O2's (providing the cats work) to make a hypothesis of "is it ignition or is it fuel." Oh and props to whoever put the battery in that car haha. With the price of all the adapters the could have bought the correct battery 😂 Cheers, Eric O.

[@theroyaltyautoservice]

I totally understand what you're saying. I think it was a Scott Shotten class that I saw the FT differences. It should be easy enough to prove out one way or the other. I'll see if I can do something next week. Will definitely let you know what I find. Yeah, the battery was very interesting. He said that was his CPAC battery and he was going to get the right one. Plus the broken positive terminal. SMH. Thanks!

[@SouthMainAuto]

@@theroyaltyautoservice Scott is a sharp dude. It'll be interesting what you find. I experimented a long time ago with it and just found that watching the rear O2's was pretty spot on 👍🏼 See you at TST

Oh man Mac Vandenbrink I used to take his classes up in Grand Rapids MI at the Autowares Conference. What a great guy and genius with the Allen Test Center Oscilloscope. I was sad to hear of his passing in 2020 but his knowledge lives on in the many training videos that are still available from his TST seminars and others. As well as those of us who had the pleasure of learning directly from him in his classes.

[@ThunderbirdRocket]

Wanna know how tremendous your coaching / teaching techniques are ? I’m able to grasp the lesson keys simply by LISTENING to the presentation . (Sometimes you can’t watch the screen when certain tasks require my attention to other things) ; but it’s A-OK due to the detail and priorities which you are saying in your coaching cues which make it clear in those instances of listening only ! Thanks so much my good mate ! 👍🏼🔥🎯

[@billsmith2212]

With the labor involved , it doesn't pay to put in off brand parts . Today's joke on batteries : years ago , I think on Chevy Nova's they would but in large engines and up size the batteries - TOP terminal . There was almost no room for a large battery . I have heard of slamming the hood and the battery shorted out . Plus if not secured , a few good bumps and you get a surprise ! 😂 Great fix !

[@jeffcompton6937]

Love these in depth videos. It such a great example of how true professionals in our industry approach diagnostics. Thank you guys

[@jdtractorman7445]

Nice diagnosis. I like how Ford and other scan tool manufacturers have made it so you can do a compression test with the scan tool. That helps immensely. Can you imagine doing all cylinders the old-fashioned way by putting a gauge in each cylinder? Like you mentioned, some cylinders are impossible to access as well. You forgot to recommend a bungee cord to hold the battery down. 🤣🤣🤣

[@JimmyMakingitwork]

These cheap parts can cost lots of time and money since once you install any "new part" you assume it couldn't be that. But the past couple of years not only COULD it be the new part if there is still a problem, is MOST likely is THE new part. These Escapes love to Fry PCM's also. I've seen the coils exploded dozens of times with no control signal from the driver. But glad to see it was just the coil (and plugs) for this customer.

[@jerrykorman7770]

Yup I’ve noticed the quality of replacement parts has taken a real nose dive

[@JamesSmith-xs7sr]

I just replaced a non charhing alt on an 06 escape, (parts store alt, oem no longer avaliable) lasted 1 week, now smoking/heatin up & such... Thankfully it was a 4 cyl engine, alt removes easily from the top of engine, no need to remove exh man heat shield either. Just lossen/rotate for alt r&r.

[@JamesSmith-xs7sr]

Those exploded/melted coils are the most putrid smell EVER! Sometimes wiping out the pcm coil control driver as well.

[@riceburner4747]

You are very diplomatic on criticisms. I HAVE to comment on that battery, working for a battery company for years. I am NOT a fan of Optima batteries. No hold down, SIDE terminals that the positive can arc on the frame, and just not the correct size. That battery bouncing around in the tray will definitely shorten the life of it. Once again, great work on your part. 👍

Great video, secondary waveform analysis is another lost art, yet such a fundamental diagnostic tool.

You can get to the other cylinders in the back. These are two wires coils and the ecm provides the pulses. So you can back probe the ecm and check the primary signals. Primary should mirror the secondary. Great video and as always great to see you're using the Escope. Thank you

[@Mr2004MCSS]

Great video. I learned some things in this one as far as the scope capture goes. You should get some of Joe Caci's secondary ignition flex wands to get some captures of the coils under the intake. He developed them for just this kind of scenario.

[@theroyaltyautoservice]

[@Mr2004MCSS]

@@theroyaltyautoservice Yes, it would be nice to see you use them. He makes some great tools.

[@marcdrouillard4055]

Hi Sherwood. These coils look like they have some magnet material in them. This makes the coils polarity sensitive on the primary side! a reverse polarity connection results in a low coil output energy. I have seen this on some Ford visteon coils that our reseach team were using on a V10 H2 ICE development engine. We had poor ignition performance when all 10 coils were reverse polarity connected on the primaries.

[@onimedia1072]

Learned this at the Audi training center and it’s game changer especially diagnosing on our V6 and V8 where swapping coils and plugs are not ideal

[@Kate_Short-For-Bob]

Great to see the process of detecting the problem scientifically. (Ive played swap-shop when coil packs have failed on a previous car (VW Group car) when on holiday as i only had a simple £10 OBD reader with me, and it would report which cylinder was mis-firing. Swap bits around and the fault moved to a different cylinder. Confirmed it was the coil pack and got one at a parts store at the nearest town. But defo better to do the investigation 'properly'. (I had another coil pack go down 2 weeks later - id maybe have picked that up early with proper kit)

On the 3.6 pentastar I don’t mind pulling the intake off to swap coils. I’ve done tons of them and takes me maybe 10-15 to pull the intake. But some are a nightmare to pull.

[@FACTSAutomotive219]

The ATS, and most aftermarket tools are nowhere quick enough to actually "show" the misfire in the o2 sensor. IF you use a snap on, and graph only the o2's you can and will see a misfire in the o2's and how they react. My topdon, autel, ats, launch, none of those are able to plot the data smooth/quick enough. The other tools just do not graph quick enough. Fuel trims on a single cylinder misfire are very tough to prove out. A quick test for any misfire is to grab a intake pressure pulse and relative compression. That will guide and funnel the misfire quickly (as I know you already know this Sherwood. This is for the followers)

[@danigrumbles520]

Swapping was how a mechanic recently attempted to DX a misfire for me. He then sent it back because she wouldn't misfire again. My dad used to work as a tech so he offered to pull the plugs to swap them (they were 10 years old & I'm looking to keep) and look over the coils well. Found oil in two of the wells. If we hadn't decided to dig deeper, how long could I have missed that the valve cover gasket was needed? 😶😶😶

I love that your took the time to diagnose the issue but a simple coil swap from the suspect cylinder to another good cylinder would have given you clue if the coil was good or not. 5 minutes is all you need to diagnose coil performance without a scanner

The coil windings are not backwards the connector is upside down changing polarity with the wires that is wild

[@rogeronslow1498]

The coil manufacturer screwed up the winding phase. The result is the output voltage will be a negative spike rather than positive. The plug should fire but it'll erode the ground electrode rather than center one.

[@cruze1953]

I think it is the connector being upside down causing it as shown on camera.
