Question about Mercury Grand Marquis
I don't know about yours, but some cars are wired to run the pump off the oil pressure switch, after the car is running. You probably need to consult a wiring diagram to see how the pump is wired to power, and then try to solve it. Most unusual!

Sure, the more the throttle and the longer its open the more gas is being injected so if the spark is not there it will spotter. I think you have nothing to loose with an ignition tune-up. It'll be more economical than taking it to a mechanic and still ending up with the same problem. You should change the fuel filter also it could be clogged and there is'nt enough fuel delivered at these speeds. You can also try a fuel injector cleaning solution the kind you pour in the gas tank. This might work for you.
