Chev Impala 2001, 3.4 I just bought a few months ago.
When changing gear from P to Drive, the car can hardly move, or move very
slow. I have to press gas pedal to get the car move forward. It's not like
any car I ever used. However, if switching from P to Reverse, the car backs
up pretty fast (or say, normal). Is it a problem? or a kind of factory
setting? Is it related to idle speed?
Thanks for any advice.
