I need help to understand secondary waveform on a Audi 100 1988 ignition with a distributor and Bosch mono jettronic fuel injection,Throttle body injection.
Fixed a problem with rich condition and car runs great now passed inspection CO 0,8. But I don't like the secondary ignition waveforms no experience with scope but I now how a good secondary waveform looks like.
I used the MI074 Secondary Ignition Pickup.
Cyl1
Cyl 2. I understand that the waveform is showing both rich and lean but is it interference from other cylinders in the waveform or is it only the probed spark plug wire that I have on the waveform.
Yes plugs replaced my thinking is if all the captured trace is from the probed wire or is it noise from some other spark plugs wire. upload a capture from king lead.
