Code 43 Miss on all #1-#6

Took the 96 to Advance and had the code pulled Miss on all cylinders. Hmm I replaced TPS with no change. Looking into Cap wires and plugs. Anyone have the similiar problem with a bucking cherokee?

Start checking sensors. Knock. cam position, and crank position.

I had the exact same ordeal with my 97. I looked and saw that the 02 sensor in the cat had frayed wires and I replaced it and its all set now. I'd take a look at your 02's. It was bucking for about 8 months before I figured out what it was.
