i know this may sound silly but have you checked the Transmission Fluid? i have a 99 cougar and it was jumping aswell when the fluid was leaking. hope this helps
yes
pink
no, after '93 the interior style changed along with the door panels, they will fit on the door, but you will not be able to close the door unless you have the '94 and up dash
Remove the gas cap. If you do not hear the pressure release, then press the shrader valve located on the fuel rail.
YES
1993 is obd 1 and the connecter is under the hood.
check the temperature control sensor....
If it is a 5.0 from a 1991-93 Thunderbird/Cougar, then yes
the '93 cougar can swap parts with any cougar between '89 and '96. Since you have a '93, I'm guessing it's an XR-7 (performance) model, so try to find other XR-7's. You can also interchange parts with the Ford Thunderbird of the same model years.
If they both share the same engine, yes
yes if the other car is also a 4.6
