Yeah, I’m fighting a hesitation/ miss in my daughters ‘02 f150. Not throwing any codes yet. Only shows up at first acceleration, and then if your cruising along, and get on the gas a little. Other than that, runs smooth.
Ohm’d out all the coil packs, and they are all within spec. Checked across the connection as well as to where it connects to the the plug. Boots looked fine also, with no visible cracks.
Did the “stethoscope” check with a long screwdriver on the injectors, and they are all firing away. All sounded exactly the same.
I’m trying to take the diagnostic route before I start throwing more money at. The fuel tank was just changed out, along with a lot of the evap system hoses. Top of tank was rusted out. I just ordered a fuel filter just in case that got fouled up with everything that got changed. Hasn’t been done in a while, so I figured that was $20 well spent. We’ll see where that leads me.
