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.

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.

@shanersmechaniclife3164 8 ай бұрын

This was the fix for this particular misfire. Condensation in the intercooler is also a problem on these. Drilling a hole ( in the proper spot) is a fix. It's definitely a misfire prone motor. Thanks for watching.

It was a scary first time experience so I decided to take it easy since the trip was a 2 1/2 hour trip and that problem happened at the start of my trip. I still had to return home later that night.
