Need your mechanic thoughts

Still blowing out 2015 Fords, Nice price, best pickup on the road...it's a win win

Your comments on the electrical sparks made me go back to this thread to see if you ever figured out your issue.

Changed out O2 sensor and plugs/wires. Took care of my lean codes. I was still getting a P0300 random misfire code. Took it to another mechanic friend that took care of that. I'm guessing it was simple because he didn't charge me and gave me a stick of moose summer sausage. It still has a bit of a miss at idle that I can't figure out.

So did you blow up your old truck like Si Robertson did or were you able to get it run better?

 

[DirtyMike]

It's running. Still throws a misfire code every once in a while. My mechanic friend says we'll worry about it when its warmer out. His shop isn't heated. Something about a fuel pressure regulator sensor. Sounds made up.

If you thrown a muffler bearing is wore out it could cause the computer to trip a code.
