Hello all,

I got a nissan altima 2004 , 2.5S. When I let off gas the rpm drops quickly
as you can see on the youtube video below, and bounce a lot. Also the car jerks
on acceleration and deceleration mainly from 1 to 2 or 2 to 1. It looks the
transmission has delayed shifting ...
I have no idea what is going on, I have searched the net a lot but I could not figured it out yet ... I'm not sure but I think I have this problem after I changed my alternator...
Nissan would charge 100$ just to diagnose the problem...
Appreciate it if you can help me...

Replace your negative battery cable assembly.

Any engine codes? Any loss of power?

Any engine codes? Any loss of power?
I have not scanned the engine but there is no light on. No loss of power. The RPM is kind of drop and jump when I let off gas, like it suddenly drops to 1000 and jump up to 1200 and again drop to 1000. jerky shifting is also more noticeable from 1 to 2 than 2 to 3.

It is a drive by wire system...could just be a faulty pedal sensor?
