95 Ranger dies while braking hard in nuetral
I have a 1995 Ranger with almost 180,000 miles on it. It is of the 2.3L 2wd variety. My problem arose a few days ago.My truck died while i was coasting downhill. I might have had the radio up a little loud so i didn't realize it, and when i went to turn, no PS, my right front right front fender and a gaurdrail made friends. 
I've realized it only happens when breaking hard in nuetral. The CEL is on with code P1443- Evaporative Emission Control System control System Control Valve. AutoZone doesn't carry this. Is it a dealer item only? Would this cause this problem. Drove fine with CEL for well over 6 months. I've recently replaced the fuel filter, so thats not it. Have a full tank of gas, and have ran fuel injector cleaner through. Any help would be greatly appreciated.

Welcome to FTE!
How is the idle, any problems with that? The Idle Air Control (IAC) valve controls idle and is also is repsonsible for making sure the engine doesn't stall upon deceleration (it's called a "dashpot" function).
Why are you procrastinating on fixing the EVAP code? You should keep in mind that the PCM makes fuel and timing adjustments with operation of the EVAP system in mind. For example, the PCM is programmed to reduce fuel injection pulse time when fuel vapors are being routed backed into the upper intake (i.e., when the cannister purge valve is open) and mixed with the air/fuel charge. This is done in order to maintain the proper a/f ratio. If the system is not functioning correctly, there is a good chance that these adjustments are still being made even though they shouldn't be.
And keep in mind too that it isn't necessarily the purge valve that is malfunctioning. This thread has some very good information on the subject:

It surges a little on idle, but not horrible. The Haynes manual didn't have too much on the EVAP code, thanks for the thread - lots of good info. I'll try and fix that when i've got time. If the Fuel/Air ratio is out of whack it can cause it to run to lean or to rich and die I'm guessing.
