I have a 2004 lincoln ls and it has code p0443 and I replaced the purge valve and it still brings the code up after I reset it..i checked the wiring and it's ok...and it idles ruff and goes into gear very ruff..earlier today I tried to switch the pcm but the one I had was from junkyard and didn't start my car..after I put my old one back in, then it ran beautiful without check engine light..i drive it for about a couple miles then parked it..went to start it and now it's running like shit again..any ideas?
