Is your check engine light on and flashing? Want to know why? Want to know how you can find the problem?

In this video I have a Ford F150 with a 3.5L Ecoboost with that problem and a misfire on acceleration. Watch  as I explain why the check engine light is flashing and use my Snap On scan tool to find out what and where the problem is. I also explain some common issues and show you what to look for.

Stay tuned till the end and watch me demonstrate an economically priced bluetooth scan tool that you can get from Amazon. That way hopefully you can diagnose your own check engine light next time it comes on.

Be safe and wear your safety glasses and other necessary safety gear.

This just saved me 300 dollars I appreciate it a lot

[matttyxm]

Thank you for the tips and info about BlueDriver. Very helpful!

[pedroquintana]

thank you this worked perfectly for my suv👏

[superBryce]

Thanks for taking the time to do this video, I know its a lot of work by itself. Hopefully this scenario is my problem, my 2017 f150 3.5 Eco boost. I get a flashing CE light when accelerating, it goes away when the vehicle calms down. I do loose power so I know the fuel injectors are shutting down. Thank you again.

[briansawdo]

Thank you for the info. I just went ahead and changed all my coil packs and all my plugs and it took the problem away. I cleared the codes and the check engine light went out but then probably about a week and a half ago. The check engine light came back on. I believe it’s for an oxygen sensor. I haven’t thrown the tester back on it yet but the truck is still running smooth. I’ve got 301, 000 miles on it. I’m sure a couple of things are going to get finicky.

Thank you have the same truck with PO306 great video I’m going to replace all 6 coils and spark plugs great video will be waiting for more updates

[DarkWaterEva]

Great video and truly appreciate your time with this video. I do wish though, you used the bluetooth device along side your more professional scanner when the vehicle had that problem to just demonstrate the bluetooth's capabilities. Anyway nice video.

[fozziebear]

I have been having the same problem on my 2013 F150 Eccoboost. DO I have to scan with the light flashing? Mine always turns off after a minute or so.

[DarrylHopkins-iq]

Very helpful howuch would repair cost

[jessejurado]

great info, thank you flashing light on my2013 i also have blue driver just wanted too see what anyone else had to say about this isue

[MrLookingtolearn]

Just had this happen last night 2021 f150 3.5L. Was at highway speeds went to pass big rig and check engine light began flashing and very rough fluttering..pulled over, parked it and shut it off. Restart after 1 min. Continue to travel at 115km cruise. For another 4hrs. No issues since. Should I be worried? No warning lights at all

Drilling a hole with a 1/16 bit into the turbo intercooler stops this issue as water is building up in the intercooler itself. What you did is only a temporary fix, it will happen again.

[eriksony]

Thanks for sharing, Do you still work on Ford cars?

[RandallPress]

Great video. Most likely that’s my issue.

[keithstarnes]

Fixing to go check mine now. 2014 F150 with turbo, stock, flashing light just happened during passing. Went off when I decelerated. About 107K miles.

[samgonzalez]

I’m on a p0304 code I Rr the coil and ohm th injector but when I moved the injector th misfire stayed win four and another to number 6 . I am waiting for my ecu and one injector on a 2017 f150 3.5 ecoboost.

[joseespino]

Give me the link to buy the blue Driver Scaner Please.

[jaredl.]

The check engine light blinks when I turn the ignition on, but I have not had any misfires after replacing the plugs. Is it a remaining code or is there still an existing issue?

[marianovalero]

Hey Shaners Mechanic could you be so kind and enlighten me... a bit frustrated about an issue of my 2013 F150 ecoboost 5.3 misfire cyl # 6. however watching your video am a bit confused about where exactly is cylinder # try to save some money and looking to change coil #6 Thank you in advance great video.

[paulmelissastanfordrealtor]

I have the same thing happening to my 2014 Ecoboost. Changed plugs and coils and am still having misfiring. Moved coils and misfire moved ro totally different cylinders than the couls exchanged. What could the problem be??
