I just recently acquired a used cvt, low mileage and all...
I've noticed a vibration problem when the car comes to a full stop. The
RPMS tend to drop pretty quicky between 1100 to 800 rpm (when deaccelerating
down to a complete stop) and there is a noticeable vibration kicking in. On
acceleration and at cruising speeds the vibes are no where to be felt and is
smoother than slicing butter.
I did bring the car for a check and they claimed that it had something to do
with the air throttle body which was dirty and prevented the valve from
moving freely. They cleaned that up, and it seem to provide relief for a
short distance of driving, but is clearly back as a problem.
Is this normal ? If it isn't, any ideas of what the problem could be ?
fyi: the ignition coils were replaced supposedly sometime in 2003.
