My Fathers Mazda B3000 is misfiring badly. We have changed the Plugs, wires, coil pack and air filter. We ran a coder on it and it stated that 5 and 6 where misfiring. We have check the plugs and wires even though there new and we still cant find anything wrong with it.
Do you
have the same problem?

Engine running rough or misfiring can be cause by the following-inspect and test all the following listed below:
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.
