2003 350z. I checked threads but still no fix
 

My slip light and vdc lights are on. Car wont go over 2000rpms, i reset ecu, but removing battery and depressing brake, also let it sit over night with battery disconnected, codes still lit, and still wont rev. Parts i threw at it are, maf sensor, throttle body, accelerator position sensor. Still say problen.. I checked the air filter its dry. I may have done more just can't think of what... I had the codes. See if i can find my notes. Any help will be appreciated.

Welcome- but posting a question like this is better placed in the "maintenance and repair" section. It also helps to know exactly what codes were being shown, both before and after you threw a bunch of parts at it. The diagnostic system in your Z will only activate limp mode if you have a code that could cause safety issues or serious engine damage, so why did you replace the other parts in the first place?
