hi i bought a power performance 68mm throttle body i installed it with a blox tps when i tryed to calibrate the tps sensor it only went up to 3.6 volts at wide open throttle so i bought another 1 but still did the samething so its throwing a CEL anyone know whats wrong?????

 

Is the TB adjustment bolt threaded all the way up? If so, thread it down so you can open the butterfly more.

 

yeah that was the problem thank you very much
