Hi,
swapped engine from jza70 into to 7m chassis. And having a problem with revving the engine.
Idles perfect, starts perfect , but when revving the engine. It hits like fuel cut on 2000rpm.
Harness extended by myself.

Checked vaccum,
swaped map sensor,
no mil codes,
tps works,
swapped ecus ( Mines and stock),
checked engines ground,

anything else to think about ?

Could be a bad cam or crank sensor.

Also make sure the coils are good. There most likely cracked.
