Re: Cam Position Sensor

["TK" <terryk@foothill.net>]

Yep, I'm in California. We get the better stuff here. 8^)

I grabbed a cam sensor from a 3100 SFI and I recall pulling it from the
front of the intake or block just behind the pulley's. I don't have a  3.1L
MPFI here but it just sticks in my head that *when* it's there, it was in
place of the dummy oil drive in the dist hole.

Anyone that can clarify this?

Bruce wants to know!
