The spark plug

As far as I know, iridium spark plugs are built to run 100,000 miles. They were made for hard to install cars, like minivans and some new cars like the Nissan Versa.
I wouldn't recommend it, since it will do the same job as the platinum spark plugs, plus you'll be saving a ton of cash, iridium spark plugs could go up as $34.00 each.

Your car has a coil on plug ignition system. So, you would replace the spark plugs, air filter, cabin air filter and PCV Valve. There are no spark plug wires, distributor cap or rotor and the fuel filter is in the tank, not requiring replacement for the life of the vehicle.

CHECK FOR SPARK AT SPARK PLUGS, CHECK CRANKSHAFT SENSOR, CHECK FUEL PERSURE, ALSO CHECK FOR INJECTOR PLUSATION.

The problem is in the ignition control module. Check it and make sure it is getting power to the module.

Hello, check your PCV valve, also must of us get a tune up done and never change the Fuel Filter. Also i recommend that with a timing light you make sure your spark plugs are all firing, that the spark plug cables are in good shape, not internally oxidatedand they where install in the correct order. Good luck, God Bless.

plug prices are the same regardless and the engine is the same just with a bit bigger pistons
next time use an accredited service center and not a shop mechanic
