My 5.7 L engine on my Suburban was running rough. I changed the plugs and while better it still is a little rough. I was going to change the plug wires but thought I might need to also change the distributer. Is there a trick to getting the distributer off as it is at the back of the engine and is hard to tell how it is held on? I don't want to take it apart and not be able to get it back on or tear it up getting it off. Do I even need to do this?

Engine running rough or misfiring can be cause by the following:

1. Defective spark plug
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
11. Idle air control valve.
