I'd start with the basic tune up and then work outward from there.

Post again after you've replaced the plugs, wires, rotor cap, rotor, battery, air filter and fuel filter.

Is the '88 Mark VII EFI equipped? If so, I would suspect the IAC(Idle Air Control) valve. A simple R&R.

try adjusting idle to approx 500-600 rpms ,,,clean egr valve,your basic tune up and MOST importantly adjust tps to approx .99 +- .1volt i did everything and all seems to be much better the tps was actually the thing that did it ....its not hard to do ya just gotta mess with it
