2009 Nissan Altima

I have a 09 also and @80 I turn 2050RPM, does yours accelerate good ,does it pull all the way till you reach desired speed/ if it does there is nothing wrong its a cabalistic of the CV trans.

Does it accelerate fine when you push on the gas hard or does it hesitate ?

Yup, it is a "cabalistic", LOL

My peddle feel heavy

When I hit the gas

What's a cabalistic ??

cabalistic = characteristic.... It went horribly wrong using a spell checker would be my guess. Really hit me right in the funny bone.

If it drives fine up until you’re going out of town or driving 60mph - 80mph for and extended period of time let’s say 30 minutes straight then it acts as if it’s not accelerating it may be your catalytic converters or o2 sensors I had the same problem
