Bucking

[irish237]

the other night i was driving my 04 mazda3 s and noticed that if i accelerate when in first gear and let off the gas (no foot on clutch) when the car is coming down from say 2500 rpms as it comes down to about 1100 rpms it starts bucking as its going down? any chance anyone can explain whats happening there?

Our cars have notoriously bad mounts, they were built around dampening as the paramount factor, problem is the end result give you a soft squishy pos rubber inserts that allow and ass load of play especailly as they deteriorate after time, I' am thinking the tranny mount, good thing is there are high quality after market pieces to changes these out with.
