2003 ford expedition. P0320 was created by gerber
Hello guys. I got 2003 ford expedition 5.4. With the code p0320 . Whats doing is when driving around 70 mph makes a backfire not to loud . For 3 seconds then goes back to normal sometimes it those around 40mph So i start my diagnostic at the coil they look original. And the truck has 200xxxx miles
This is the. Wave form that i got. (First picture at idle looks ok for me)
And this is the fould that i see when driving around 70mph wave form **secound picture *** wich make me think my crank sensor .
I know my crank sensor. Can be Getting short out at high rpm. I will check that too.
Alredy check the wiring on the crank and its fine. Any recomendation will be appreciated. Thank you
