Hey guys,
I discovered the rough idling was caused by a faulty ignition coil (5/2). I used a multimeter to test the resistance on each coil and I found the (5/2) coil was dead or faulty. The other set on the pack shown a normal reading between 0.3 to 1.5 ohms approximately. Any reading below or higher than the normal considered faulty.
I'm still having trouble solving those code: P0449 (EVAP), P0206 (Fuel Injector), P0300 (Cylinder misfire).
Its possible the P0300 is due to spark plugs being un-gaped. I would have to check those out.
