94, Grand char limited, Backfire/no power

Looking at picking up a 94 Grand Charokee limited. Problem with jeep is:

Backfiring and lose of power.

I have not had a chance to go check it out yet but hoping I can get some ideas on what to check.

Been done:
Plugs/wires/O2 sensor/timing belt was checked and said to be good.


Wondering if plug wires could be reversed or leaky intake?

Does any one have a small diagram of how the plug wires route to each cylinder?

Any ideas what to check would be most helpfull

Thanks

Rich

Doesn't have a timing belt, but a timing chain. The firing order is the standard 1-8-4-3-6-5-7-2. 1 being left front from driver's seat.
Check distributor cap and rotor, rotation is clockwise.
Compression test.

If it's a 4 liter, the #1 plug wire boot easily gets torn if someone isn't careful when removing it (don't ask me how i know that). If it's torn, it'll arc to ground and cause a miss. Something else to look at would be ignition coil output, but you may have a hard time starting it if the output voltage from the coil was too low. It would certainly cause your other symptoms though.

Hope that helps.
