1988 Jeep Cherokee 5 liter motor straight 6. Runs one day, and then the next day, no power to the spark plugs. It seems to have a mind of its own.

2001 Jeep Cherokee Sport - sometimes sputters and has no power at start up. Sometimes the check engine light comes on. I had the code checked and it said 3 rd cylinder failed to fire. I imagine it could have a different cylinder each time or it could always be #3. I have changed the coil packs (the plug wires and coils are in a single self contained unit) as well as the spark plugs. I thought thi would fix it no luck. It still does it sometimes. Any thoughts?
