Compare waveform with different frequency

Re: Vw golf 1.6 runs bad

Hello, no there are no dtc's, already performed the throttle body adaptation also tried another throttle body, also reset the learned values in the ecu. Still runs bad when hot. Going to make some captures of the lambda sensor tonight.

Re: Vw golf 1.6 runs bad

It was with lambda connected, yes it is switching, seems good to me, forgot to save the waveform, but will make a new capture tomorrow.
