Having some issues with my Infiniti J30t. I know this isn't an Infiniti Forum but I know for sure they use this same engine in the 300z so hoping to get some advice. About 25-30 percent of the time when the vehicle is warm and I start from a dead stop, the car lacks power big time! Almost feels like the car is in 3rd gear from a start or even over drive. I have manually downshifted though before to first and still is sluggish. I have changed the plugs, fuel filter and air filter and still does it. Any suggestions?
