Re: 82 eldorado 4.1
No, if that's the case, it's not the switch. Probably an idle control problem. I forget how the 4.1 is controlled. It's carbureted as I recall. Probably just needs an adjustment.
I don't recall if that year had the fuel pump wired to the oil pressure switch or not, but if it did, I believe that the engine would not run if it failed, foot on gas or not.
P.S.
Please do not start new threads on the same subject. No one will ever be able to follow along. I merged these two.
