Potentiometer to the MAP Sensor what the ... ?
Today I noticed a green plug right by the fire wall with nothing plugged into it sticking outside of the wire harnes conduit housing a green, a black, and a gray wire, which runs to the MAP (Manifold Absolute Pressure) sensor mounted above the driver side wheel well.
Where does this supposed to go I wondered as I followed the harness?
Then I found a lump of electrical tape wrapped around that wire harness about a foot away from the MAP, curiousity got the best of me so I unwrapped it. What I found hidden under it was a basic shiny potentiometer spliced into the green wire.
What the heck is that supposed to do?

It definitely is not supposed to be there... They may have been attempting to modify the MAP output for what ever reason... Good luck with that 85. Those 2.8L with the E2SE carbs are a royal PAIN!

so true
"Those 2.8L with the E2SE carbs are a royal PAIN!" - swartlkk, you can say that again!!!
People stay away from these under powered 2.8L V6s, something has to be broken at all times, they don't like to be fixed.
How I wish I had the '94 Vortec 4300 4.3 L V6 fuel injected 200 HP, does anybody wanna trade, mine will make a helluva mechanic out of anybody, LOL.
