Accelerator Stuck problems of the 1998 Mercury Villager

My 1998 Mercury Villager Mini van has a problem with the accelerator. The pedal can be hard to push sometimes causing to push down too far. Several times the accelerator became stuck causing the vehicle to lunge out of control. I felt very unsafe and I am concerned about the condition.

Bought used 1998 Mercury Villager in June, 2004. From June through present date, we have had accelerator pedal sticking in upright position causing lurching from a stopped position due to having to press down unusually hard to accelerate. Due to this "failure", I do not want to crash into someone in front of me in traffic to move forward into traffic from a stopped or slowed position. I have sprayed wd40 on the pedal from inside the vehicle that relieved the problem for a little while, but it has started sticking again.

The accelerator pedal some times sticks were you can not give it gas. This has been happening for about 3 yrs. It causes fear, because you if you had to speed up some time it will not let you.

Accelerator pedal sticking intermittently. Dealer was not notified at this time. Feel free to provide any further details on this matter.

Accelerator pedal sticks, at any speed. Consumer has to press pedal hard to get it to unstuck, problem getting worse. Dealer said throttle body needs to be replaced.
