Hey guys I have recently installed a aem cold air intake for my 2003 350z and when I started the car the vdc, slip, abs comes out straight away and does not turn off, didn’t do that before though, anyone have an idea what could be, my speedo still works

 

Ever think of seeing if it is throwing any codes, or putting it back the way it was before to see if it goes away?

 

some ppl's troubleshooting skills aren't that great.
but maybe OP has tried that already

 

I doubt it

 

Brake fluid low is my bet
