doing a head and cam swap on a 98 trans am and broke a sensor or plug on the back driver side of the motor. Im having trouble uploading a pic i took earlier. its the shape of a bic lighter and has a green clip at the top of it. If anyone has any idea of what it is i would appreciate it.

 

If you broke it pulling the intake, then it's most likely the oil presure sensor. You and several hundred other people have done that.

 

Sounds like the Oil Pressure Sensor as stated. Common thing to break. Just be sure to get the right replacement as the 98 F-body has a different sensor than the 99-02 F-bodies.

 

ok great. thanks for the quick response. and yes it broke while pulling off the intake.

 

several hundred? more like several thousand............

 

I broke one once after the intake was already off the car
