Problem... Help Please.
 

I have Automatic car.. (i Know i need a 5speed) But my problem is that when im traveling around at a higher speed like 25-40 MPH then i let off the gas it like 30 seconds to go back to 1500 RPM.. my car never use to do that. Like it will stay at 3500-4000 RPMs for a while..

i have replaced my spark plugs, and wires, and caps and it doesnt fix this..
i was thinkin its the tranny but the car only has 120,000 KM on it

any help would be great... Thanks In advance.

does your car feel heavy?

yeah... a little...

I'm finding it hard understanding what your trying to describe.

Are you sure you not driving with the hand brake on? lol, osrry had to ask that!

give us a starting speed and an ending speed and the time that has elapsed. make sure your on straight ground..
