Default Engine Swap Questions

Hello,
recently i completed my Mini Me Swap

1996 Honda Civic Dx Automatic obd2a

When i was doing this swap, i did everything as if the swapped head was d16y8
it wasn't until i got to the distributor(its didn't bolt on right), that i looked at the stamp on the engine head, and it said

p08-2 with is a d16z6 head :/

so Now here is my set-up

96 y7 block
94 z6 head
p2p ecu
auto tranny
z6 dizzy - rewire to obd2a
y7 spark wires
y8 intake
y8 pcv valve
y8 fuel rail and injectors
y7 throttle body with y8 rotor
fixed the p0453 code using option 3 on this site
.:FFS TechNet : OBD2 Code 91 Issue & Fix :.
wire vtec to ecu and it kicks
mechanical and electrical timing are checked and right on.
coolant is bled
as of now no CEL lights

the only problem i have now, it that after starting the car when its warm, it will idle fine with a smooth vacuum, but right after i give it gas and rev it, the idle will drop from 750 to 450. also the oil pressure drops with that from 0-4 psi


i dont know what could be causing this.

Any hint?
if theres any other info needed i will tell ya guys

Thanks

Is your IACV clean, and wired properly?

Also check your TPS calibration (0.4 volts from center wire to ground with throttle closed). The voltage should start low and increase as the throttle is opened (do this test with key on but engine not running) If the voltage is reversed, you need to swap the two outside wires.

Oil pressure will naturally drop as the engine slows to zero.

Yes when i did the swap i took apart the IAVC and cleaned it out, and since its an automatic, i didn't need to do any rewiring.

For the tps - i just tested it, and it read .479v closed and then increase when i open the trottle to 4.55v

Also my gear shifting (automatic ) it rough on the 1st gear, it wasn't like that before the swap, it seems as if it slips for a bit and then catches on, or sometimes its just rough with delay.
but all the gears, shifts are smooth, just the 1st drop is fought
