i replaced the switch 90 bucks pep boys in stock. 2 hours of dash removal and 20 minutes of replacement time and it kicked right over. I WAS BLOWN AWAY... still cautious but it ran amazing well like new! tranny, shifting, even the service engine light went off... it had been blinking for 2 years. no one could ever diagnose it? code there one minute gone the next... yaaa! i can get smogged now and get registration finally stop looking in mirror.
thanks guys

The ignition switch fault will NOT make your vehicle stall. That is a fact. It has exactly zero to do with engine tune.
Now we're knowing what the SES light blinking in the other thread is. It is not blinking. It comes on sometimes, and sometimes it is out. SES lights do not blink. Multiple threads will make HARD diagnosis too.
