There could be many many many causes for this as this is a very general question. Best thing to do would be to go get the code read at your local auto parts store. Now if your not able to repair it yourself you would be better off to take it to a mechanic and get the code read there

What causes a 1999 Mercury Marquis to hesitate when accelerate?

Several things need to be checked if a 1999 Mercury Grand Marquis is hesitating when accelerating. Does the hesitation only last a few seconds until the car is slightly warm? Do you hear a poping noice from the engine compartment? Is the check engine light on ? I have had similar problems and this type of problem is typically caused by air or fuel problems. 1999 Mercury Grand Marquis are fuel injected and any vaccume leaks can cause these type of problems. I would check all hoses to make sure they are secure. I would check the PVC valvs, I will check to make sure none of the hoses are blocked, I would check the idle air control valve and its passage, I would check the EGR valve and its passage, I would check the throttle body and bypass valve as all of these items can be gunked with carbon deposits. This should be a good beginning point but the answers to my questions will really help to narrow down the issue.
