Hello I'm working on a 00 f350 4x4 auto 180k
Miles. It has a random misfire occasionally. It may be
Fine for 3 days then run like crap for 1/2 a day them be ok again.
I have pulled valve covers checked harnesses, there good clean
And tight. Replaced icp. Had oil in plug. New cam sensor yesterday
Has not acted up since but I'd stil like to ck codes. Ses light is not on
But occasionally it will come on for maybe 1/4 a second then go out
It's fast enough ill barely catch it in corner of my eye.
I'd like to see if any codes are stored I anyone can help.
Thanks
Chris

 

It may be worth giving your IPR a look, just to make sure it's in order. Like the tin nut is snug and the harness is in good shape.
I had been getting intermittent low ICP readings and the truck wouldn't get out if it's own way at times. I was looming some wires in the bay real quick with the truck running and it sputtered and shut off.
Ok... I've got wires making contact somehow. Unplugged the IPR and saw the 2 wires clearly contacting each other in the plug. It's unlikely, but might be worth checking.

 

I can pull some with my tuner, but not all like an A&E or snap-on will. I'm in Marietta.
