Cylinder 5 misfire?
Now a new thing happen. Car trembles at idle now. So many damn things presenting itself. 0604. I also got 1302 map baro switch. But 0604 today. Is it coil pack or spark plug? I can't check till a few hours so a little advice of what to expect would be nice. Thanks

For the 0604, try swapping the coil with cylinder #3 or #1 and see if the problem moves with the coil. That will help you isolate a bad coil pack.
If moving the coil does not move the problem, check for a blackened or wet spark plug on #5. We are seeing a few injector o-ring failures that result in cylinder flooding. I think this is purely coincidental but we are seeing the number of injector failures increase over the past 12 months. A leaking injector o-ring usually leaves some tell tale signs of flooding on the cylinder where the misfire is occurring.

I got it. It was pretty easy. Thank god it was the coil pack. 60$ each. Thanks for location. I think it was still original coil for 200k miles. Unless it was another oem. Said nissan on it
