Background: I just bought this car.

The engine doesn't run smoothly, (or as smoothly as it should) especially at start up, it gets a little better after it warms up. I was going to replace the wires, but they are expensive and I want to make sure I'm not wasting my money.

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.
