So I just replaced the coil pack on my 2004 Xterra 3.3ltr 6 cylinder and now when I drive down the road it will skip sometimes not all the time but it never did this before the coil pack went out, what could be causing this skip?
Please clarify some details for us, what do you mean by 'coil pack' and 'skipping'? First generation Xterra's have distributors, not coil packs.
They also have torsion bar springs in front and leaf springs in the back.
