I just got my G back today after having a set of Nismo headers installed by a local Infiniti dealership. Now the Service Engine light keeps flashing and the idle is bit more rough. The only other major mod I have are the Nismo camshafts.

I don't mind the idle too much, but the I would really like the figure out how to get that light off.

I have a 2003 G35 Coupe 6MT.

Any suggestions would be appreciated.

 

go back to the dealer or go to a kragen and get them to read the OBD2 code

 

Actually I did ask them what the computer said when they hooked it up and they said it didn't say anything, just kind of went blank.

I took it to an Autozone and had them read the code. It read as a misfire which has been coming up every once in a while since I had the camshafts installed about 1 year and half ago.

 

Sounds like a bad O2 sensor...or one is messed up.

Misfire errors - P0300-P0306 can indicate a lot of things - fuel pressure, spark, O2 sensors, bad coil, etc...

Verify the code is one for the above - I'll send ya troubleshooting related to it.
