Hello Scotty! Love your channel. I have a 2014 Ford Expedition Limited with a 5.4L Triton Engine. It has 210,000 miles with an automatic transmission. I am getting a misfire when I step on the accelerator and my speed is between 40 - 60 miles per hour. Problem is that I am getting no codes, no check engine light. How can I find what the problem is with no codes to read? I've read that you can read extra codes with a mode 6 scanner but not sure if my Zurick ZR13 can do this. Please help. Thank you.
How can I find what the problem is with no codes to read?
How about recording live data while the problem is happening and playing it back?
My Zurick ZR13 does read live data. I will take a look at that.
When was the last time the fuel filter was changed and have you pressure tested the fuel pump?

Fuel filter was replaced about 6 months ago but I have not pressure tested the fuel pump.
