CAR HAS A HARD TIME PASSING 2000RPM-2500RPM

2004 Infiniti G35 • 130,000 miles

The vehicle is very slow off the start and has a hard time accelerating over2000rpm.
I changed he cam shaft sensor and the problem got worse.

P0021 for Intake cam position timing-check the oil if sludged-up

P0011: http://www.obd-codes.com/p0011

P001 and P0021 are both for the Intake Valve Control and it could be due to sludged oil causing the control valves to stick or the control valves are faulty.
