Thanks in advance for any help... Just bought a 1997 Explorer and it is acting up since... rough idle and poor power. Had a friend test it and showed a misfire error on 1 and 4 cylinder. The plugs all white (lean) no sign of poor combustion? I checked everything I could imagine... Any guidance would be greatly appreciated! Thanks! Mike
1997 4.0 OHV Explorer Error Cylinder 1 & 4 Misfiring

Intake manifold sealing failures are well documented with the 4.0.... since both of these cylinders are located at the very front of the motor, I would spend some time checking out the possibility of an intake leak - especially at the front of the manifold.
HTH.
I can't remember which cylinders share a coil, but if cylinders 1 and 4 share a coil , it could be the coil pack thats no good.
I just pulled the intake manifold off last night... will get new gasket set and try it again... THANK YOU!!!
