My Stang is Sick....Please Help Her

[Black1987Stang]

My cars got a weird problem, it will run fine as long as im moving and driving, once I idle for over 10 seconds or so it will start running really rich? (exhaust has a smell to it anyway), it will lope like it has a huge cam in it, idles like crap period, has a really bad off idle stumple, vacuum drops down to 8 inches from a normal 12 inches, loss of power, and bucks pretty badly like a new driver driving a stick. It will stay in this "mode" pretty much as long as the engines running, but if I turn the car off and start it back up its GONE and it will repeat again if i let it idle for 10+ seconds or so again. I have no codes, except for things that are deleted or I dont have (like VSS).....It never used to do this, all I can think of is the maf or the intake air temp sensor and since they both have to do with timing and the air/fuel ratio management....but then wouldnt they set off a code if they were that much out of range? btw the O2 sensors have less than 10k on them...... Im lost, please help me out

Figured it out, put on another maf and now runs sooooo smooth, starts right up in the morning, dont even need to give it any gas or anything, I got it from a V6 Taurus too I think ill pick up another as a spare.

Use a 94-95 Mustang MAF, it is 70 MM and a direct swap. The V6 & V8 MAF are the same for 94-95, so either one will. do. Use the electronic sensor that comes with the MAF, it is a direct plug in fit. All you need is the adapter for the air duct. http://www.kustomz.com/cat3.html

Buy the TR70 for $44.95.
