SOURCE: 1989 jaguar xjs v12 fuel mixture

Chances are the coolant temperature sensor or its wiring have failed, or the vacuum line to the MAP sensor is leaky or broken (I believe the V12 in '89 guise uses MAP sensors). The MAP sensor measures Manifold Absolute Pressure. Along with this pressure the ECU looks at engine RPM. It also measures air temperature. Knowing pressure and temperature we know density, and knowing engine speed tells us how much volume of air is going through the engine. All of this together is computed into air mass and is used to calculate how much fuel mass should be admitted. If the vacuum line is broken, the ECU reads less vacuum and produces rich mixture thinking that the engine is under high load.

SOURCE: 1989 ford mustang power window will not go down

check the pwer switch. if you don't detect any sign of live. then you have to open the door panel to check the motor. most likely the motor or the "T" rail cable is broken.

94 ford mustang 3.8 engine why is no. 5 cylendre running too rich

How do you know #5 is running rich? error codes tell you that? I doubt it. But if you are sure, check the connections and the wire all the way back to the Ecu. my wild guess, the control is shorted to a positive supply and therefore the injector thinks it is supposed to supply wide open fuel. Or you have a bad ecu that is telling it the same thing.

I need to know if the vaccume lines on my 89 mustang 5.0 are going the the right place. Is there a diogram or a picture to look at?

There should be in a motors manual or maybe your local parts house has access to michell's manual's on line. Going to pick up a new book today on our 88 GT converible.

1989 ford f250 a/c only comes out through the defroster

More them likely you have a vaccum leak, check vaccum line that gose into fire wall under hood make sure it has vaccum, if don't find vaccum hose and repair, if it does check vaccum hose under dash follow it make sure it's plug in, if it is could be a bad vaccum pull off or bend door or the selector switch. Good luck hope this was helpful.
