Traction control problems
 

I have an 03 escalade base model,and the traction control comes on while I'm driving.I have to pull over and turn the car off and restart it so I can drive.Its taking longer and longer for the tc to go off.changed alternator,two front hub assembly,throttle body,mass intake sensor,all four 02 sensors,and it still keeps happening.It runs great this has been my only issue with this vehicle.can anyone help me.I love this vehicle.

Code(s)?

p0171 and p0174 are the only ones that come up.

Those are lean engine codes, indicating a vacuum leak normally, they should turn on service engine soon light. It could be cause by hose of back of intake manifold or intake gasket not sealing.

ABS codes normally relate to traction control
