Fuel injection voltage waveform

Working on a 95 gmc safari 4.3 liter with an intermittent stalling condition and was wanting feedback on my voltage waveform. When the transister turns on it begins sloping up till the transistor turns off. Any ideas as to why? I know these jumper harnesses usually go bad inside the intake manifold. Is that what im seeing? Any feedback would be appreciated 

Please clarify what exactly you did scope as the picture is too foggy to get the scope settings...

I "assume" this is tbi - although none of the two traces looks like tbi. If so, I´d further assume you captured the voltage on the control side of both injectors, didn´t you? Or does the second, green trace happen to to be an amperage reading of the same injector as the red trace/controlside voltage shows? Probably not...

So I assume a bit more: The red trace shows 2 spikes, the first one happens when the "peak driver" let go and the second shows the "hold" driver shutting off. Nevertheles I do not see any pulses during the "hold period".

A better picture would be awesome.....
