1998 GMC K1500 Sierra SL, ECM/Inputs/Outputs Waveform
Posted to the Waveform Library on 2/1/2014

another wave of number 1 volts with all inj current. Do u see the inconsistent amperage draw of current for the injectors? This could confuse the pcm . Normal current draw for 1 inj should be less than 1 amp.
