Hello everyone I'm not sure if the theme refers specifically to Carberry, but I drive it, in a 100% SD mod. The problems started with the mixture, it was not stable at idle, fluctuated between 13.5-15.5 AFR, so I started by checking the spare parts. I cleaned the nozzles, bought a new original lambda, moved the IAT to receiver, checked all the gaskets and tightness, without any effect.

Later, I accidentally noticed that with smooth acceleration, or holding the rpm, the engine speed graph looks sawtooth. Obviously, this is not a healthy situation and I associate the problems of the mixture with it. Has anyone come across something like this? What could be the reason? I can't even imagine how and what to check here, excluding the crankshaft position sensor and the reference gear which are very reliable and do not wear out.
