check engine light, AGAIN
 

OK, here it is again. This darn light is driving me nuts. I changed the EGR valve as suggested, it worked fine for a few miles then the light came on again. I put a scanner again and it came back with the same code P1443. My search this time mentioned the Purge Control Solenoid or Purge Control Valve. Should I change these out as well? Do you recommend anything else.
thanks,

I never read your first post, what year is your stang? What does the code say in your manual/book. The purge controls are part of the Evaporative emissions system and have nothing to do with the EGR system, so maybe i'm missing something.
Unfortunately if it is an evaporative emissions problem, the only way to diagnose is by getting the resistance specs for the components and measuring, by jumpering the correct terminals and seeing if solenoids activate or by using a "smoke" machine and seeing if there's leaks or if activating a solenoid will make the smoke travel through the solenoid.

Ok, its a 96 stang with 75k miles. I got the car in 2001. After the first tune-up (plugs, wires, fuel, air and oil filters the light came on and has been going off and on since then).
I replaced 2 O2 sensors already, along with the EGR valve. This weekend I replaced the PFE valve along with the selonid regulator. It was ok up ot 25 miles then it came back on. The code that was given out was P1443. (emissions control system control valve) I've change out almost all of those parts and still get the light. I even reset the PCM after the change out. This little light is getting to be expensive. Any other suggestions.
