R32 gtr with 34 nur motor. Weird idle.
 

Hello all.
my name is Yury. I’ve had my skyline since t became legal here so 15 years. Been a long working project.
ran into a problem which I can’t figure out and I’ve tried to find a similar problem and haven’t had much luck.
move changed my tps, spark plugs, igniter and coil harness. Coil packs are spitfires.
Cleaned my iac and mafs. I have a tomei fuel pump on standby.

im posting two links. One is the a video of the tach showing the problem and the other of my pfc during said problem.
it only happens after warm up and while driving is fine.

any help would be greatly appreciated.
