Not sure about the filter, I was guessing that myself. Bought the car 6 months ago. Odd thing though, it'll start up in park now. Same idle problem till warmed up and even then it idles under one, borderline choking out. Don't have a neutral safety switch.
Also don't know if this ties into it at all but a light on my "automatic light" dials which tells me the lights are on works... never has until now and I haven't played around with any electrical with the car.
BTW sexy T-Bird you have there, what's it get 10 mpg
