i got p0121 after ls6 intake install. also the traction control off light stays on and when i put the car in drive it surges on and off meaning the idle is funky. i already know what this code means to a certain extent. anyone?

DTC P0121 TP Sensor Circuit Insufficient Activity
What else did you do besides install the intake?

I just installed my LS6 intake this weekend. It was pretty straight forward, the worst part was unhooking everything from the back of the stock intake and getting all te harnesses/fuel rails out of the way.

Only code I got is for the EGR, since it isn't hooked up.

The DTC for P0121 is "Throttle Position Sensor A Circuit Range/Performance", so I would check to make sure you hooked the harness back up to the TPS. If it is hooked up, pull it apart, clean it with some MAF/electronics cleaner, and pt it back in. Maybe it just has a bad connection.

problem solved. these problems i was having was ALL because i rewired my map sensor wire harness wrong after i ripped it out on accident trying to take the intake out the 3rd fucking time It is confirmed, a messed up map sensor wire will set off a tps code.
