04 Lincoln Nav on a cold start humming then dies on idle
Seems to only do this on a cold start but car starts fine then as we drive about 2 miles the car starts this loud high pitch humming noise, then as we get to a stop light the noise gets louder then the car shutters then dies... it starts right back up but then same thing when we get to a stop, loud noise, shutter, dies.
The other day i wanted to see what would happen when i put it in neutral and gave it gas, it stopped the noise for a min then 1 mile down the road it started the noise again, sputter, die.
any ideas? took it to auto zone they hooked the comp to it and it reads nothing... she said it's because the engine light is not on.
