I recently changed the spark plugs on my 350z and after I did it it has been idling rough as well as shaking whenever it is stationary. It also makes a weird clunking noise when driving sometimes and the left side of the engine bay is shaking way more than the other side. I’m not sure what it is. If anyone has an idea anything would help!

 

You prob swapped a couple coil pack plugs by mistake

 

Alright I’ll look to see if I accidentally did that. Thanks for the tip!

 

Swap 4 and 6. Must be that time of year... third coil swap this week. 😆
