I have a 2007 Nissan Murano SL with 134k miles that almost feels as if it’s pulsating while accelerating and lurches at lower RPMs. When I rev it to higher RPMs while driving the lurching goes away. It also has a very noticeable lack of power and the car feels pretty sluggish. I’ve replaced all spark plugs and ignition coils. The only codes I’ve ever gotten have been engine misfires. I’m at a loss for what to do so any help would be greatly appreciated.
