A bad sound and witholding in acceleration

i have a 1991 chrysler grand voager, recently i noticed that when i accelerate the car witholds its speed , and the car can not move as accelerated,and next the dash board reads - check engine. i have changed the fuel filter and the problem is still there.Emmanuel

Why so many posts??? Have you noticed any other problems with the way the vehicle running? Which engine do you have? How many miles does it have on it? How fast can you get the car to go? The first thing that comes to my mind is a plugged catalytic converter. If this is the case, you will have very limited top speed, usually around 20mph, and the engine will not rev freely. Your engine will also have sort of a ‘vacuum cleaner’ sound to it when it is running. This is just an ‘off the top of my head’ guess, but once we get some more information, we will be better able to help you.

That check engine light is the vehicle trying to say to you, “Take me to a mechanic.” If you go to an auto parts store or mechanic, they will hook a computer up to your car to see why the check engine light is on. Some auto parts stores will do this for free. Once you have the alphanumeric codes (usually something like P0510), post them here.

Well, this is a 91 model. He’s going to have to take it to a mechanic to scan it.


Thanks for your first response, the car has 160209 km on it ,and the speed 20mph(60km/ph)at which the problem starts,yes the sort of sound is like a vaccum cleaner.funny enough , i was driving down a slope one day and expected it to freely accelerate but it never did. thanks.
