I am thinking coils. But with no code I am not sure. Both injectors and MAF. Any ideas?

 

My guess is coils. Next?

 

Does your check engine light work?

 

Most likely coils and I have all 6 brand new nissan oem coils for sale. if they are the coils that are bad let me know are go to the classified section on this site and click 4th gen parts and you will see the post for my coils on sale and a link.

 

Use a timing light and check your coilpacks....for missing! If it's not the coilpacks at least drop 1 cylinder at a time and monitor your engine rpm's with an analyzer and record the rpm amount each cylinder drops and if the miss disappears....the cylinder with the largest rpm drop are the strong performers, the cylinder with least amount of rpm drop are suspect! Once you Identify the weak performers pull your coilpacks and plugs and inspect for any obvious defects...if nothing obvious is found measure the sparkplug resistance and I would swap with a plug from a strong cylinder to see if the problem transfers if it doesn't, I would inspect all the injector connectors for security, and check each injector's resistance. If all looks good try some STP fuel treatment you got bad gas!
