Micsig SATO1004 Injector Waveform

Using the Micsig SATO1004 Automotive Scope to look at a fuel injector on a 99 Mazda B2500 2.5L. In the video, when I execute 3 throttle snaps, the wave form gets pretty wonky. I think it’s possibly a shorted injector due to the straight up line on the current ramp, and the weak to no voltage spike. I see something very similar in Paul Danner’s (scanner danner) diagnostic book. I am always learning, and always will be. Put in the comments why you think the waveform looks like that. I think I’ll either clean, replace, or clean test, then replace them, and test again; so we can see the differences of each on the scope. If you want to see more on the this scope SATO1004, the ATO1104, or the STO1104E; subscribe and go to my channel to see plenty, and more to come. Thanks everyone.
