Cam sensor

Being a newbie this may create a few laughs ,
The cam sensor can be installed 180 out. The tangs on the inside will only go one way but the body can be seated in two places .
We instaled one everything went home no problem but car would only fire sometimes . After 2 days saw a pic of a camsensor and the guy was putting the bolt in and the connection was up . Went out pulled the sensor flipped the body 180 and it went right back home again hit the key switch and varoom she fired and ran.
SO watch not only the tangs on the shaft but also the body position
another thing is you have to have the crossover tube from the breather to tthe throttle body installed to make it run
