M102 2.0 Rough idle, not accelerating

VulpesIgnis

My M102 2.0 struggles to start and when it does, it has a rough idle, when I try to accelerate it will rev up a little bit and then fall back. Very hard to describe, but my injectors fire in an oscillating manner, I will upload the recording of the commander.

In the recording, the car shut off by itself. When the idle input shuts off I am flooring the gas pedal.

Alright, the idle issues were caused by the faulty tachometer gauge interfering with the AN signal, however I am still having acceleration issues, whenever the rpms go above 3500, the ECU seems to bug out and the injection shuts off.

Alright, problem solved.
The ignition coil seemed to not be able to hold spark for more than 3500 rpm and made the TSZ go insane.
