Need help ASAP!!!! 01 f150 missing on idle and during regular drive gear
I recently installed a 4.6 in my 01 ford. Ever since it's been acting up. I replaced the EGR valve and spark plugs. The computer is showing EGR flow is out of range. It shakes when in normal drive gear but smooths out in passing gear. I've disconnected each coil pack with the truck running and they all seem to be working I love the truck and the power it is supposed to have.
