I'd concentrate on idle air control valve. IAC valve. They control engine idle speed.

SOURCE: just trying to find a wiring diagram for a 95

Visit the autozone.com website and register the car information. It doesn't cost anything and you will gain access to an online repair manual for the car. The wiring diagrams should be available there and the manual is a handy resource for anyone doing their own maintenance. I hope you find it helpful. Best wishes.

Its time to do a injector balance and cylinder leakage test, to determine whether the injector or its circuitry is bad . The leakage test will tell you if the cylinder has a compression leak.

Need a spark plug diagram


Hello,

Take a look at this picture. This is from a 94 cougar V8, on the left and right are coil packs with wires coming out and going to the sides of the engine. On the spark plug side you pull to remove, on the coil side squeeze the clips and pull up. IMPORTANT - Do one wire at a time so that you put the wires in the same spot as you took them off.

Good engine swap for a 94 grand grand marquis


Another 4.6 out of a '94 Grand Marquis. If you can. That way all the sensors will be correct and the wiring harness will plug-and-play. You can install almost any 4.6 but, depending on the year, there's going to be a lot of issues making them work with the electronics in your '94 Marquis.

1997 mecury cougar v8 engine. Wont start. It is


Not sure if you got your cougar running or not, but I had a similar problem and it turned out to be my Crank shaft sensor. I replaced it myself, its fairly easy if you are the type that likes to pull stuff apart and fix it. The part cost about $20. you do have to move the ac compressor over but you don't have to remove it makes the job a lot easier. I am still running the 1997 cougar xr7 30th anniversary edition, it has 160000 miles on it and still running strong. I think these are the best cars mercury ever built, i hope they come out with them again in this body style and platform.
