I have a 2001 infiniti I30 it had ses light on with p0170 and p0174, took it to mechanic they said it was intake manifold, so replaced it, after being repaired. I now notice that the car has hard slow starts it takes more than one try to start it,also it seems to be losing power, once I reach 60mph it won't accelerate past that. The rpm goes up but car moves sluggish and won't go beyond 60.

Check the fuel pressure if it's within specs.

Could be caused by one of the following below:

1.Vacuum leaks
2.EGR and PCV valve.
3.Low fuel pressure.
4.Dirty fuel injectors.
5.Mass Air Flow Sensor.
6.Oxygen Sensor.
