i have a 93 grand marquis now at start up it idles very low and starts shaking however after 5 minutes it is fine and for the rest of the day no matter how often i start the vehicle. it seems to only happen when the car sits over night. i know there is no manual choke due to the fuel injection but can there be a electronic choke? any ideas would be greatly appreciated

Yes there exist and aftermarket electronic choke..Check it out on your dealer...sure they have one there. I heard that Grand Marquis has a durable Mercury Oxygen Sensor...how true was that? I'm looking forward to own one but just still looking for reviews and actual experiences with it.
