Hello, I bought a turtleneck as in the subject and I would like to get an opinion on it, in addition to something slightly jarmola at idle on the right side of the engine, such noises as grinding pepper in a Vag grinder shows a low voltage lambada heating error (lambda probes) and sporadic engine failures stepper, I will add that it waves slightly at idle speed (sometimes) when it warms up and when it lights up, it can go out right after the start and you need to fire again.
