Question about 2007 Chrysler PT Cruiser Touring Hatchback
A P0304 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #4.--------
Symptoms may include:--------
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.-----------------
This should help.Thanks.Helpmech.

My parents car is doing this. I did a tune up (plugs and wires) and it still continued. I looked up a wiring diagram and the coil pack has 2 sides 1/2 and 3/4. If it's throwing a po304 the 3/4 side could be bad on the coil. That's what was happening in my parents car. Other than that you could have bad injectors or even a bad fuel pump.
