The check engine light was flashing off and on as if trying to determine what was going on. So after I got home, I started driving in my neighborhood until the check engine light remained on.
Finally, my cheap gps Garmin diagnostics showed a P0304 code showing up.
Cool, I been through this with cylinder one a few years ago and got all new coils back then too. Initially, I replaced all my spark plugs mid way thru ownership to be proactive to prevent future problems.
In reality I probably changed them too early. So presumably some of these spark plugs are going bad since I’m nearly running on 13 yrs and nearly 110k miles.
So I took one of my 3 old oem spark plugs I kept in the drawer and sprayed some throttle cleaner to remove some of the carbon. Placed some dielectric grease on the coil. Boom done!
While in there, I also replaced the pcv valve.
Now my Rogue is driving smooth like butter again. It’s a great feeling to fix something in 30-45 minutes and probably save over $500 instead of going to the dealership.
But I still love going to a Nissan dealership if the work is too backbreaking for me, or I’m too lazy, or the convenience of it all.
But it’s so satisfying for us commoner’s to fix our vehicles unlike before the internet where growing up I wouldn’t know what a misfire let alone being able to change a spark plug before the World Wide Web. Compuserve anyone?
Well anyways, it’s great we can still work on these old school cars before everything becomes electric and regular people will get clueless again.
Ps- I also kept my 3 remaining old oem coils as back up too.
