I'm not getting spark from 2 ignition coils, do these need changed?

To Remove......
1. Remove the spark plug wire from the ignition coil.
2. Disconnect the ignition coil electrical connector.
3. Remove ignition coil bolts.
4. Remove ignition coil.

To Install.....
1. Install ignition coil.
2. Install ignition coil bolts.
3. Tighten ignition coil bolts to 8 Nm the same as 71 inch pounds.
4. Connect ignition coil electrical connector.
5. And finally, install spark plug wire to ignition coil.

Look more closely at the 1 and 4 coil, also, check for trigger signal to these coils. I mostly suspect the trigger unit.

The P0302 code means that the cylinder 2 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 2. If the problem persist more tests needs to be done to diagnose problem, see "Possible Causes"
- Faulty spark plug 2
- Clogged or faulty fuel injector 2
- Faulty ignition coil 2
- Fuel injector 2 harness is open or shorted
- Fuel injector 2 circuit poor electrical connection
- Ignition coil 2 harness is open or shorted
- Ignition coil 2 circuit poor electrical connection
- Insufficient cylinder 2 compression
- Incorrect fuel pressure
- Intake air leak

more than likely your spark plugs they should be changed every 60,000km

These engines have 3 coils and are paired 1 and 4 2 and 5 3 and 6 with a spark noid run to see if the paired cylinder has no spark if so remove coil from module and test the power supply to coil and with a logic probe test the trigger side if blinking with no spark your coil is bad. not blinking replace module.

PLUGS ARE EASY JUST #1 IS BEHIND ALTERNATOR, IF YOU TAKE OFF INTAKE, YOU CAN GET TO THE BACK 3, OR FROM UNDERNEATH AND UP WITH 2 SWIVELS.THE COIL PACK IS SMALL 8MM? LONG BOLTS, VERY EASY SWAP OUT. CHANGE WIRES ALSO, 1 OFF 1 ON IS EASIEST WAY

O2 sensors get changed at 100,000 miles
Has that been done?

Has the TPS Sensor been tested with a scan tool
or oscilloscope?

Have you cleaned the MAF Sensor

All these items should be part of your preventative
maintenance,just as spark plugs

There is no need what so ever to change wires or coil,
unless they are tested & fail a test

need more info (need to know what type of ignition system your vehicle has: (1) traditional ignition coil /distributor system, or (2) electronic ignition, but lack of spark problems are usually a faulty coil
on traditional vehicles, and on the newer electronic ignition cars, total lack of spark would be
a faulty ECM (electronic control module) - partial lack of spark (diagnosed with a HEI (high energy ignition) spark tester kit), would be caused by a faulty coil pack (in the waste spark system), where
there's 1 coil pack for every 2 spark plugs.
I bought my HEI igntion testere kit for $20, but Harbor Freight sells a similar unit for $10.
Hope this helps.

Hope this helps. The ignition coil:

• changes low-voltage pulses from the PCM to high-voltage pulses.
• fires 2 spark plugs simultaneously.
• has 3 transformers.
  • One transformer fires the spark plugs for cylinders 1 and 5
  • One transformer fires the spark plugs for cylinders 2 and 6
  • One transformer fires the spark plugs for cylinders 3 and 4

Spark plug wires:

• carry high-voltage pulses from the ignition coil to the spark plugs.

The spark plugs:

• change high-voltage pulses to spark at the gap, which ignites the fuel and air mixture.

The firing order is 1-4-2-5-3-6.

You may have a sensor problem, or an ignition problem. I would need more info to help you.

My 2004 Verona had factory installed "NGK BKUR6ETB" regular spark plugs which I replaced at 30,000 miles. The 2005 model year is supposed to have Iridium spark plugs. To replace the spark plugs: 1. Remove plastic top engine cover. 5 nuts 10mm socket. 2. Unplug connector from each ignition coil. qty 6. 3. remove 2 hold down bolts per ignition coil. 10mm socket. 4. remove ignition coil, lifting straight up. 5. Spark plug is now accessible, use deep well 5/8 spark plug socket to remove.
