Coil packs I replaced #4 and #5 went out. Why?


How to Tell if You Have a Faulty Coil Pac How a Coil Pack Works When creating a spark at the spark plug, the fire must initiate from a high voltage supply, so as much fuel as possible burns in the cylinder. Whenever the combustion process is started, the coil pack builds up the energy, as much as 50,000 to 75,000 Volts. When the electronic control module (the car computer) sends the signal to the ignition control, the voltage is released from the coil pack through the spark plug cables to the spark plug.
When the spark travels to the spark plug, it jumps from the spark plug gap to the ground, causing an explosion of the fuel air mixture inside the cylinder chamber Coil Pack Problems Usually, if a coil pack is bad, there will be a loss of fire or spark in one or more cylinders. This causes what's commonly referred to as misfiring. Misfiring can cause drag on the crankshaft, and usually results in a very poor performing engine Common Symptoms of a Faulty Coil Pack A faulty coil pack will generally have symptoms similar to a faulty spark plug. Some of the most common tell tale signs that a coil may be defective include:
  • A rough idle
  • An unexplainably louder-than-usual engine
  • A noticeable lack of power
  • A significant drop in RPMs while accelerating for no apparent reason
  • A blinking or intermittently activating check engine light
  • An active gas warning light when the vehicle has plenty of gasoline
  • Smoke from the exhaust emitting intermittently, instead of in a steady strea How to Test a Coil Pack Fortunately, there is an easy way to test the coil packs in your vehicle and make sure they're working as they should. You need to use ohm meter to test the coil pack for continuity. Make sure you have the approximate ohm values for the coil pack. To find this information, research your car's engine on the Internet or purchase a Chilton's or Haynes manual to find out what the mega ohms reading on the coil pack should be. What Coil Pack Works with a Rotary Engine? Most rotary engines require a different type of ignition coil pack. Below are two, one for a standard replacement, and one that is a higher voltage performance type coil pack.
    Original Equipment Replacement
    Beck Arnley is a well known name in the automotive ignition parts industry. They are favored by many mechanics, especially those that work mostly on import cars. The Beck Arnley 178-8025 rotary engine coil pack is a direct replacement for original equipment parts on older Mazda cars with a rotary engine. You can expect to pay about $55 for one.Performance Replacement
    M&W Ignition Systems is a fairly well known name in the import performance market. Their part number PAK005 is a high performance ignition coil pack for the performance enthusiast who isn't afraid to spend a little more on a high quality high performance part. With prices running around $245 for a double coil pack for direct fire ignitions, these coil packs will deliver years of excellent performance.
    When ordering a coil pack for your rotary engine equipped car, you need to know the year and model as well as the engine displacement to ensure you are given the correct parts.

My husband replaced the coil pack in our 1991 dodge caravan and now it is backfiring and acts like it is out of time. What is the firing order for this vehicle? it has the 3.3 liter engine


Sounds like he has the wiring missed wired at the coil pack, or the wrong replacement. There should have been a wiring diagram that came with the coil pack, recheck, I think you'll find the trouble is there

Misfire p0303


Check wiring harness around and including plug to the coil pack. Also check fuel pressure with vehicle running. I'm not sure of the specs but, Iit should be around 35 to 40 psi. at idle, and 50 to 75 at higher RPM's. I've seen Fords run with a bad fuel pump and demonstrate these exact symptoms

Obd code po353 4.6 engine and firing order


You can look up any code on google by typing in OBD 2 code: XXXXX and you will get a number of hits and explanations as to what to do. From what you show, it sounds like the spark plug wires may be on in the wrong order or you are getting a misfire due to a fouled spark plug, bad spark plug wire or even possibly a bad coil pack or distributor depending on which you vehicle has. A lot of newer cars have coil packs instead of a distributor and each pack usualy has two connectors. If you put them on in the wrong order or matched up the wrong cylinder with the wrong coil pack, you may need to get a repair manual from an auto parts store which describes what order they go into. Once you have tried this, you will need to clear the code with an OBD2 scanner or by removing the battery terminals and reconnecting it after a few minutes. The bummer is that you may have to reset all your radio stations and your clock. :(

P0304 code-Misfire on cylinder 4


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:--------
  • the engine may be harder to start.
  • the engine may stumble / stumble, and/or hesitate.
  • other symptoms may also be present.
--------------- A code P0304 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.
  • ---------------------
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.-----------------
This should help.Thanks.Helpmech.

2001 Cadillac Deville won't stay on after turning key in ignition unless foot is on gas pedal, if foot is off, car is off?


EIther the IAC or throttle postion sensor is dirty or faulty. Or leaky vacuum hose somewhere. As long as it is not missing and running weird, then you may have bad coil packs.
