We need excalty your Cadi year, cylinder number and model to send this answer.

A code P0304 (Misfire #4) may mean that one or more of the following has happened:
* Faulty spark plug or wire
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector
* Burned exhaust valve
* Faulty catalytic converter(s)
* Running out of fuel
* Poor compression
* Defective computer

Possible Solutions:
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
* If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Spark plug one and four which one is that 2004 chevrolet trailblazer six cyl.


Number one is closest to bumper then just count back they go in order 1-2-3-4-5-6 then the firing order is 1-5-3-6-2-4 also if your having a misfire check for lose wire and if I remember right those had a problem with water contaminating the coil packs check for white on the coil and on the boot inside and out, if they are chalky you need to replace the contaminated parts and the seal to keep water out at the back of motor where hood closes.

Misfire on number 2 cyl


Cylinders are numbered from front to rear (grille to firewall) passenger side: 1-2-3, driver's side: 4-5-6. Firing order is 1-4-2-5-3-6
Did you check by pulling #2 out while the engine is in idle to see no weakness from the engine? BTW your coil pack cost $80.

How do i plug in the spark plug coils? what order?


If it's the four cyl., the first coil pack bolts over the #2 spark plug. The #2 coil pack wire plugs into #3 spark plug. The number two coil pack bolts directly over the number four spark plug, and the #2 coil pack wire plugs into the #4 plug. The firing order is 1-4-2-3.
