[91 Plus]

How many grounds are there on the intake manifold?

Also here is the way I got the vacuum ran!It was not pinched at all under the intake,and I didnt hear or see any leaks!

Also is this open or closed?
Rear

Front

I also found this plug and I do not know what its for?It is right below the oil sending unit,any thoughts?

It looks to me like only 1 ground, on the back passenger support bolt (when looking at the car from the front.)
It's a 15mm nut on a stud that screws out w/ a 19mm wrench.


On the secondaries on a 1991- if you manually open the throttle (push where the cable connects) you can actually watch them open and close. And it's fun to hear the engine revving up close.

Maybe your green circle is a low oil light sensor??
