Hey!
My 350z is acting up.
When fully depressing the accelerator the z seems to "sputter" or "stall". This happens basically everytime when accelerating hard. If it does rev up, it will stall for a while when the RPM's reach high 5 or 6 when it changes the gear. I mean that it dies and there is a significant "BUMP" as it is almost stopping for a while. That can't be too good.
Any ideas?

I made this video;

.......whats a kickdown...?

 

Kickdown -

Urban dictionary: (Engineering / Automotive Engineering) a method of changing gear in a car with automatic transmission, by fully depressing the accelerator

Wikipedia: Throttle kickdown
Most automatic transmissions include some means of forcing a downshift into the lowest possible gear ratio if the throttle pedal is fully depressed. In many older designs, kickdown is accomplished by mechanically actuating a valve inside the transmission. Most modern designs use a solenoid-operated valve that is triggered by a switch on the throttle linkage or by the engine control unit (ECU) in response to an abrupt increase in engine power.

I've never heard of it either, but I've only driven manuals for my entire life.

That being said, what's the year of your car, mods, service history, etc. etc.?? Read the sticky that tells you how to ask questions in this forum. Thanks.

 

hahaha wtf!!!

 

Thanks for the notice.
Just changed the oil and checked everything at a shop so everything _should_ be fine.

 

Nobody recognizes this problem?

Thanks,
