Hey guys just got my first 03 Z with a new 95k DE motor installed by previous owner and i’m having an issue where when i give it full throttle no matter what gear (usually low gears) it seems to not have full HP, sorta like it just doesn’t want to give it 100% power. Sounds like a misfire on idle, doesn’t feel like a misfire.
Better example: 1st gear WOT slowly accelerates up to 4,000-5,000 rpms slower and slower and i have to shift into second, still WOT and same thing. Goes for all gears.

Seller lied and you didn't research hr motor,and bought a rigged car
1. p1211
2. p1564
3. p1610
4. p0304 (cleared the code yesterday and hast came back)
Probably should have led with that.
1211 is related to the TCS control unit which could be related to TCS, VDC, or ABS. That could be the cause of your problems if it is cutting power since it is sensing wheelspin or something similar.
1564 is for the cruise control switch on the steering wheel. Probably not the cause of power loss unless your ECM is bad.
1610 is a NATS malfunction. This is part of the vehicle immobilizer/anti-theft system. If you can start and drive it, probably not the issue.
0304 is a cylinder 4 misfire. This could be the likely culprit, especially if it sounds like it is misfiring at idle. Check plugs, ignition coils, etc.

interesting okay, i mean it hasn’t misfired ever since 2 days ago now when i got the car but it the 1211 code doesn’t clean no matter what and whenever i want to drive the car i have to turn VDC off or traction control whatever u want to call it. Once i start driving with VDC off a slip light comes on
