Am I missing something?
Long story short the throttle body I put on I was only temporarily borrowing from a friend so I had to return it to him after only about a week of using it. The next week (yesterday) the ls2 throttle body I ordered for myself arrived and i installed it.
The car seems to run fine but I am getting these codes now-
P1220 TP sensor 2 Circuit –A
P0153 Heated Oxygen Sensor (HO2S) Slow Response Bank 2 Sensor 1-A
P1516 Command vs Actual Throttle Position performance (TAC ,module) -A
BTW I'm using a harness adapter I ordered online from corvette central and I double checked that everything is hooked up correctly after the throttle body install.
Any idea's why these codes would suddenly pop up?
Thanks in advance!
