INTRODUCTION
Note. For a tutorial on how to interprete injector waveforms, see WAVEFORMS - INJECTOR PATTERN TUTORIAL found in the GENERAL/GENERAL INFORMATION area. NOTE: To see a list of the other year/make/models these waveform(s) apply to, go to the top of the article.

- (Scheme 42)for the waveform.
- See the «WAVEFORM DATA TABLE #1»(/buick/regal/iii-1988-1997/remont/testing-diagnostics/#waveform-injector-31l-mfi-vin-t) for supporting data.
The Waveform Data Table is listed first. This table contains supporting information about the waveform illustration and should be used in conjunction with it.
The waveform illustration follows after the table.
Note. A description of the vehicle the waveform came from is not available.
Note. Notice how this "odd" injector bank draws more current than the "even" one listed later. While this isn't ideal, it is still within range (the vehicle still runs well).
