Ford/gm bolt circle differs.
Not without serious modification
Never had a problem up to 3,000 lbs. Make sure o/drive is off, and transmission cooler installed.
yes it is the same car just different names really good if it is the same year alot of parts off a grand marquis will fit the same year crown vic they are virtually the same car
depending on how big your rims are , a crown vic doesnt need to be modified to fit 20" rims , but in order to fit 22's or even 24's.. you need a lift kit , basically something you would install in a truck to fit bigger tires for off roading same apply's for a car
a malfunction has been detected
Put it back on?
If you mean that it shuts off while idling it could be a bad Intake Air Control (IAC) valve. Very easy to replace and costs about $50. See detailed instructions at Autoclinix.com on how to replace it on a Crown Vic.
Yes.
On a 1998 Ford Crown Victoria : Overdrive is the normally allowed position , although the transmission will not shift into overdrive until the speed is higher If the overdrive is switched off , on the gauge cluster just to the right / and above the speedometer you will see the O/D OFF warning light ( if you have the digital dash it will show overdrive off in the upper right )
my 1993 crown vic shut off with out warning while at stop light only once in a while
