I have a '99 Grand Marquis recently it started have problems at idle.
Sometimes it idles but it feels like it is idling below its normal idle
speed. When driving it doesn't have a problem at any speed, however,
occasionally when cornering it will die. The check engine light has not
come on (other than the normal times when starting or restarting). I had
the codes checked anyway and as I expected I set a code of P1507 because I
have been keeping my foot on the accelerator to keep it from dieing at
idle. Any suggestions would be greatly appreciated.
