I have a 08 Maxima, I don't have no acceleration, if I step on the gas the car barely moves, changed the spark plugs, coils and cam position sensors and nothing, I tried to use a diagnostic tool to see if it will help me bet it says that it can't communicate with the vehicle, any help will be greatly appreciated, thank you.

 

Sounds like it went into fail safe mode, Did you scan for trouble codes before you replaced anything?

 

no I didn't, and now when I connect the diagnostic, is telling me that it can't communicate whit the car.

 

Check all fuses and relays

 

dawg... it sounds like your transmission is slipping. and you have an 08 which means it has a cvt. sell it

 

Nicely done. You just gave advice on a thread that is almost 8 years old.
