4cyl engine Audi 1988 running bad smell fuel high CO 7%, tested hall effect signal and primary circuit at coil with 2 channel Pico signal line up with each other guess it is ok,
King lead from ignition coil to distributor probed with a secondary ignition probe nice pattern every time.
Cyl 1 and 2 secondary no spark line just a firing line straight up... good firing line at times can I call the ignition wire just from that and also change cap and rotor?
Checked the 02 signal (new sensor) pegged lean can happen with raw fuel in exhaust I guess making hole matter worse.
Primary current waveform is a classic perfect waveform secondary oscillation in begin nice ramp.
Can send picture latter if needed.
