I have a 2006 Ford Focus ZX4 2.0L. Car starts and idles decent. Put it in gear and it dies most times. Replaced the IAC valve, fuel pressure sensor/regulator, cleaned throttle body. Cleaned MAF sensor. Checked runner for proper operation. Checked for vaccum leaks. Cannot figure out what is going on? Has anyone ran into this before? I have NO codes either. Also when your driving and come to a stop it will die sometimes as well. Any ideas? I am going crazy here!
