Default what is this sensor?

Hi guys,

What is the sensors just beside the coolant temperature sensor with a brown connection(like an injector connection),in front of the intake?

it's because when I disconnect this sensor,my vette runs better while a laps of time.

Thank you guys!

No. Not unless the SWITCH is stuck in the "on" position and constanly running your ninth injector, making it PIG rich. The TPI guys may have more to say on the subject, though.

With limited TPI experience, I would say yes. With the switch disconnected, it can't feed a signal that would activate the injector. That doesn't mean that the 9th injector isn't leaking.

RACE ON!!!
