Acceleration paddle sticks if pressed harder

I’ve 1993 Plymouth voyager minivan with 1,00000miles on it. The problem is it accelerates very slowly and if accelerator is pressed hard it sticks and comes out when brakes are applied. Any Advice would be appreciable.

A 1993 Voyager?

Have the engine/transmission mounts inspected.

This does sound like the classic broken motor mount problem that this model was subject to, IIRC.

On the other hand, if you have this paddle problem with a Grumman canoe, replacing motor mounts is not the answer to the problem.

Thanks for your reply. No the engine/transmission mounts are not inspected. The engine was open when the timing belt was changed at around 95,000 miles. The transmission used to be very smooth before that time. Now the transmission is rough from 1st to 2nd gear.

So what do you suggest. Motor should be inspected to see if it is broken?

Have the motor mounts (and the transmission mounts) checked by a competent mechanic.

Before you drive to the mechanic, check the level, color, and odor of the transmission fluid.
If the fluid is low, add the correct specification fluid to bring the level up to the “full” mark on the dipstick.

If the fluid is any color other than red, and/or if it has a burnt odor, then you have a significant transmission problem. Begin by changing the fluid, and see if that helps. Even if the fluid color and odor is normal, if it has been more than 3 yrs/30k miles since the fluid was changed, you need to have that done.

I would have the throttle professionally cleaned to see if it resolves the sticking issue.
