| I recently had a misfire issue and took the car to a local nissan. They did a compression check and diagnostics. Diagnosis found two injectors firing but, no fuel delivery so they tried injector cleaner. After that didn't work I was told to buy new injectors. I bought 615's and found a local shop (Atlantic Auto Repair)to install because I did not want pay nissan labor. They did a really good job installing but, I still had a terrible miss. Their diagnosis was a bad ring (60 psi on #2). I was referred to a Master Mech at an Infinity dealer and went to see him. He looked and listened to the car and told me it wasn't the engine. The problem ended up being a bad ecu. I got new 615's out the deal so I'm not complaining.
