The Spark Plug Misfire Misdiagnosis In A Lincoln MKZ and How WE Fixed The REAL Problem | Denver 

That was a LOT of words for 10 seconds of useful information.

4:50 is what you're here for

I've had a lot of ford escape 3.0L that had ignition driver codes. All needed pcm.

You are so helpful! I've been racking my brain trying to figure out what's wrong with my lincoln mks ecoboost. I got it cheap and work on my own stuff. 3 mechanics before I got it tried to figure it out and I figured I'd find the problem. MY head was too big to realize I was in over my head. But your video enlightened me to investigate the electronics. Wish you were local I'd take it to you for help. Wish me luck!

Thank you, this was amazing.

I assume my issue is the ECM, as I replaced the coil, code remains and I can smell “electrical overload” on the new coil. But what diagnostic tool confirms?

great ad

You said the problem was on the 5V reference circuit, that would require a 3 plug connector at the coil wouldn't it? 1 for coil control 1 for 5V reference and 1 for 12V. The MKZ I have here in the shop now only has 2 wires to the coil. 1 for control and 1 for 12V.

Hello, I may be wrong, but I own a Lincoln MKS which to me is more like the Taurus and the MKZ more like the Fusion. But I'm not an expert

I have a hard time taking seriously an expert who thinks an MKZ and a Taurus are the same car. They are NOT, they are different platforms. MKZ=Fusion. MKS=Taurus. These are Ford's D3 Platform Cars MKZ & Fusion = 3.5NA. These are CD3 Platform cars, a platform designed by Mazda and adopted by Ford during their Mazda ownership. MKS & Taurus = 3.5 Ecoboost or 3.7NA. Another shop telling the shadetree mechanic that cars are too complicated to fix without an expert. Why didn't they show us the code? 50/50 their diagnosis on the computer being bad is complete BS and just a way to charge for a far more expensive part. $800 for the ecu as opposed to a $50 coil. Why not show us the code? Im not conviced the cars computer can distinguish between a bad coil and a bad ecu due to a bad coil. Ohh and it can cause a fire..... dont forget to warn us how dangerous it can be and the consequences of working on our own cars....

Can you recommend a shop in the Fresno California area

Taurus? You mean Fusion.

We need a shop in Atlanta ga

You talk a lot for no reason.

My 2015 Lincoln mkt smells like propane??

You didn’t explain anything about what was going on.

Dude you never had to change plugs every 5,000 miles smh even 10 k

Your smugness when you call it. A Ford Taurus is especially funny because it's a Fusion. Continental is based on the Taurus.

Dude just say the damn problem
