Car bogs down when given gas.

Car bogs down.... Any ideas? Driving down the road at 65, cruise engaged i start to slow down, but the pedal starts to go all the way to the floor. What would cause that? the car itself didn't die, it just wouldn't allow the speed to increase? 96 Cadillac Seville STS automatic. Thanks in advance.

Hi there,
This problem is most commonly caused by a weak fuel pump. It will need to be checked with a fuel pressure guage. If you can obtain a fuel pressure guage you will need to observe the fuel pressure while accellerating to see if it drops out.
good luck
