INFINITI INFINITY QX4 SENSOR PROBLEM

2001 Infiniti Infinity QX4 • 165,000 miles

I had a couple of codes come up, #1 - P1145 - intake valve timing control position sensor. (Bank 2). I replaced sensor and code went away. #2 - P1320 - Ignition signal primary. I replaced all ignition coils and spark plugs and code went away. My problem now is the unit starts up but when I throttle up it bogs down, I played with the TPS but no change. No codes are coming up, could the TPS be at fault and not throw a code? How do you set up the TPS? Am I looking in the right direction? Note: I replaced the fuel filter.
Thank You

Not the tps. Does not control bogging down. That is timing, fuel pressure or back pressure from cat.

The 1145 comes from sludge in the oil system from lack of maintenance.

The oil system has to be flushed out completely, the valve replaced and cross your fingers it will work
