    hi how are you?does it only run rough at a stop and in park,or all of the time?does the exhaust smell like gas?

    It would be a good idea to scan the computer and see if you have any misfire codes so you can pin point a cylinder for fuel or spark.

You need to have it check immediately if the CEL was Flashing.This means that your engine is experiencing a serious missfire and damage to the catalytic convertors can occur if you continue to drive it. If it was on steady then it means PCM has detected a concern and you should have it check but will not cause damage.

Can you be more clear? The pump only runs for 2 seconds until the engine starts cranking and then it stops immediately when cranking stops.

Vechicle is surging losing power at acceleration and gaining as you go along the way 2002 mertcury cougar v6 and spurtering at idle

Thanks for choosing FixYa and welcome to the site. Have you tried to change the MAP sensor or IDLE CONTROL sensor? Both of these sensors control the idle on the car. You could have another problem as well. Do you have a check engine light on?

Jumbing when accelarete maybe fuel injectors?

Check fuel injectors with a noid light for electrical pulsing issues, and by listening with a stethoscope on each injector to listen for a telltale click (indicating it's working when engine running at idle).

You have a vacuum leak. Check PCV hose on passenger rear of engine. Stuck open EGR valve can also be the cause.

Only runs ruff during park and idle.

Your EGR valve shouldn't open up during idle or the engine will run rough and may even stall. Remove it and clean the plunger and port with a wire brush and some carb cleaner. Test the diaphragm with a vacuum pump. If it doesn't work after cleaning, or the diaphragm is bad, buy a new EGR valve.
