Need help please anyone,
bought a 2006 qx56. Nice truck with 135000 miles. Bought it from an infiniti dealership in ann arbor mi.drove vehicle to mn. Vehicle drives great except during sudden acceleration to over take another vehicle, then it shutters and rpm goes up but less speed. A kind of sudden acceleration causes a rough ride, also struggles during steep hills. Maybe tune up? I use pem gasoline. Have also tried gas additive (seafoam)need help or ideas before i take it to dealer.
