i just got a 95 cougar and the thing runs extremely rich at idle to the point it chokes you from the smell.then when you put it in gear it all ways dies instantly but starts right back up again.things i've done so far consist of new plugs, wires, air filter, feul filter and cleaned the MAF sensor.dose any one have any ideas what mite be the problem and what year was it that had the eec problems

an injector is probably stuck open

not 100% sure, im sure other people will chime in

Did you try scanning for any codes? The oxygen sensors might be bad.

Maybe you damaged the MAF wires, or left some sort of resedue on the wires. I think that could lead to problems like that.

 

[mylittleblackbird]

does it idle really bad?

 

[modbird]

sounds like what I had. injector stuck open. the eec goes bad and holds one or two of them open. just get a new eec, and it should be fine. after you swap it out, run it for a while, THEN change the front two O2 sensors

i tried new o2 sensors and it is the same thing.
the cars idles fine just a really rich smell.
i cleaned the MAF lots of times so i know i didn't damage it.
now as for the eec would one out of a 4.6 grand marquis work i have one sitting in the back yard.

no it won't. You need one out of a 4.6 94-95 tbird/cougar.

About 40 bucks at the junkyard.
