Hello everyone!! I Just purchased an 09 Maxima SV sport at a bargain price! I’m excited mainly to mod it up and make it look good!

There is one thing. The check engine came up for
P0014
P0024
P0442

The engine runs rough during idle going from 500 to 900 RPM and I can just feel the engine trying to keep up when cruising. What do these codes mean and what will fix it? I’m getting into cars now so excuse my inability to be exact when explaining the issues. Thanks!!

 

Try here, every code is listed, however there is a search feature to find your specific code.

Your issues could be camshaft position sensors and EGR valve.
