This had what felt like a Ignition missfire. Tech2 was picking up miss with 7 & 8. I have Ignition secondary waveforms before and after Maff and fuel injection flush. I think I hade 2 faults. I like to post the secondary to see what you all think. If interested ? Also have Injector's primary.Ignition/Injector current at fuse box. Secondary has me a bit confused ?

Be sure to do that on another board. Test board stuff get deleted eventually.

I'm curious as to why spark went to -5 while knock retard didn't change much? Did it ping much when you mashed the throttle?

I couldn’t tell ya Mike. Did you notice this happen during full throttle acceleration? Trans shifted into second when this -5 retard. PCM strategy. I don't think the PCM did this for any kind of fault. Mark
