Welcome to the world of car repair! Would you please hear this? For the last many years, cars have been designed by people, but before being put into production, they are sent through a process with a computer where parts are designed to last only as long as the warranty, and that makes parts cost less, and the car makers and everyone involved can make more money. ( Read stockholders.)
Some many years ago, the president of GM, when addressing stockholders, said " We are not in the business to make cars, we are in the business to make money".
Were you to own another make vehicle, you would only experience a different set of problems. Sorry.

SOURCE: 1997 Grand Cherokee 4.0, ignition shuts down

The likely answer to your problem is that you have an intermittent disconnect in the ignition system. If power supply to the ignition system drops out, some fuel still goes through and when power returns it ignites in the exhaust resulting in a backfire. I would look for a bad ignition switch, or other loose connection that could me making/breaking contact intermittently.

SOURCE: what causes to burn out one of the ignition coil of 03 bmw 325i

replace the busted transistor in your ECU. For Bosch 30011 or 30014 you can use BU323Z transistor for replacement. it´s 100% pin-compatible and released for transistor ignition systems.

Right coil keeps burning out


For coils to burn it indicates either the incorrect voltage coil in use or a dead short through the primary windings or failed resistor in the circuit.
Coils come in either straight 12 volts or 12 volts start but run on 7 volts through a resistor or resistor wire . If that resistor is shorted out the 12 v on the 7 volt windings will burn out the coil . Coils are connected in parallel and never in series as that increases the amp loading on the coil windings . Check the ignition module for the second coil as it may be shorting out internally.

Ignition coils burning up


coils come in t different voltages for two different wiring applications in cars.. Let me give you a sample . Car A ignition is 12 volts so there is a 12 volt coil fitted IT starts on 12 volts and runs on 12 volts. no problem .BUT car B ignition system is divided into 2 sections The start section is 12 volts so that the coils get maximum voltage fro starting but in the run position the circuit switches to a resisted circuit so that the coil only gets 7.5 volts . Now if you put a resisted coil in a 12volt car (A) then the coil will burn out very quickly as there is no resistance circuit to protect it. The General (GM) use a resisted wire from the ignition switch to the coil so that you have 2 wires on one terminal and one wire to the distributor. Check which coils you have been using as you will see on the bottom a note --use with resistor--. Second point if you leave the ignition on and the engine is not running then there is a current that is passing through the coil and this is an electric field and that will (like and induction heater burn up the coil

My 2002 nissan infinity I35 V6 vibrates when starts. The timing seems to be of . The diagnose is that #5 cylinder is misfiring. Mechanic said its the ignition coil. I replace the ignition coil on #5...


Well, you could replace the other coils but most people wait for them to fail first.
If you replaced the coil and spark plug and the miss is still happening, it could be a faulty injector or valve problem.
The code is saying that cylinder has no power, not that it has no spark.

Engine codes P0354 P0351 engine skips low power


These codes are for a malfunctioning ignition coil/s.
P0351= ignition coil A primary/secondary circuit malfunction.
P0354= ignition coil D primary/secondary circuit malfunction.
visually check the coil packs for burn marks, damage, loose wire connectors, and the wire harness to each of the coils for damage. How long has this been happening? Has any work been done recently? Did the engine compartment recently get wet?

I have replaced the ignition module 4 times already.


Sounds like you may have a bad ignition coil also,causing the module to burn up.

How do you change the ingnition coil for a 2003 chevy trailblazer


it would not be the ignition coil....injector cleaner could help it, most people add it to the gas to help maintain clean injectors and you should do the same. as far as the coil no leave it alone.
