I have a misfires on #8 and can't figure it out. Ive moved the coils around changed plugs and moved injectors still get p0308. Any ideas why it wont move? Its a 01 f150 5.4 crew with a auto tranny. It shakes in overdrive like a bad cop.

Check compression on the cyclinder if possible.

Node light will show if injector is getting proper,signal I think.

Read wires to cop and injector.. But, like mentioned do cylinder compression test first.

Could be a flat cam on #8, or a broke valve spring.
