Hello
1992 f250 351 4x4 Only getting .1 volts at the iac. when I turn on the
ignition to run. Guess I need a computer? It gets to like 5 volts when its running
replaced all the sensors . Anybody know what the manifold vacumn should be
at idle. I am getting a steady 11 inch lbs at idle?
She runs out like 90 percent when its waemed up
Is this a mistake? My truck came with super duty cooling it said on the sticker.
My clutch fan started to squeel so I went to pep boys and they gave me a severe duty one. It was alot more heavy duty then the one that was on there.
I put it on there and it roars till it gets warmed up.

I traced the white wire with the blue tracer to where it comes out of the computer.
put the positive on the battery and the neg on the computer wire and am getting
.o1 volts. in the run position.I guess when engine is running it changes values and sends more voltage. I changed the coolant temp. twice. The new was just a little low on ohms when I changed it so I changed it again? Manafold vacumn is low? Maybe timing.
Maybe computer is messing up the timing. I didnt do a compression test but it burns like no oil.154000 miles Run local with like 700 lbs in the bed she will burn 1 quart every 2000

To start with that is a variable grounded wire by the computer and not a power wire. The IAC valve gets 12 volts ~ from the PCM Power relay (361 red wire) and the computer variably grounds the other side of the coil.

The varible ground on the iac is blue and white and I traced backed to the fire wall before it goes in the computer. and tested there to make sure it wasnt a faulty wire, In my book they
show the positive side of the iac jumping off the fuel injectors. But I am
still only getting .01 volts at the Iac?
